Part 2 about 21.7:
7. Next visit with my former psychiatrist after that from 28.4.2015 took place 21.7.2015.
8. Seventh (7th) member of arithmetical sequence starting from 3, 6, 9 is 21.
9. If we count 0 as a triangular number ("empty triangle"), 7th triangular number would be 21; if we not count 0 as a triangular number (TN), 7th TN would be 28 (21+7).
10. Sum of numbers in arithmetical sequence 33, 42, 51 divided by arithmetical mean of arithmetical sequence 3, 6, 9 is 21 ((33+42+51)(3+6+9):3))=126:(18:3)=126:6=21) and sum of numbers in arithmetical sequence 33, 42, 51 divided by sum of numbers of arithmetical sequence 3, 6, 9 is 7 ((33+42+51)3+6+9)=126:18=7).
11. Difference between sum of numbers in geometrical sequence (GS) 21, 42, 84 and sum of numbers in arithmetical sequence (AS) 33, 42, 51 is 21 ((21+42+84)-(33+42+51)=147-126=21), difference between arithmetical mean of  GS 21, 42, 84 and arithmetical mean of AS 33, 42, 51 is 7 (((21+42+84):3)-((33+42+51):3)=(147:3)-(126:3)=49-42=7), difference between sum of digits in GS 21, 42, 84 and sum of digits in AS 33, 42, 51 is 3 (21:7) ((2+1+4+2+8+4)-(3+3+4+2+5+1)=21-18=3).
12. My second going to a day hospital ended 27.1.2017 (from the digits of that date two numbers 21 and two numbers 7 can be formed, sum of numbers meaning day and month is 28 (21+7)).
13. I got certificate needed to apply for ruling of level of disability from a psychiatrist 21.7.2017 (two 21.7 phrases can be formed from that date), on that certificate F84.5, F42.2, F21 were mentioned.
14. My third full-term going to (another) day hospital started 27.4.2017 and ended 24.7.2017, these two dates are "constructed" by the same digits and have the same sum of numbers, from that dates three (21:7=3) three-term ascending arithmetical sequences with sum 21 and arithmetical mean 7 can be formed (0, 7, 14; 2, 7, 12; 4, 7, 10).
15. I experienced large coincidence 16.4.2018, from that date a geometrical sequence with sum 21 and arithmetical mean 7 can be formed (1, 4, 16), if we sort first (meaningful) digits in that date descendingly or ascendingly, we will receive arithmetical sequences with sum 7 (4, 2, 1 or 1, 2, 4), from the digits in that sequence number 21 can be formed.

I think that I got F21 diagnosis due to coincidences. If there are another people with F21-F42-F84 combination, are they having diagnosis of F21 due to coincidences which they have? And did they write about their coincidences in the Internet like I?
Before sudden onset of coincidences in IX 2014 I had small amount of coincidences in my life, for example I might think about apple and heard that word a moment after. I (at least rather) do not subscribe delusional ideas to them.

Last time I noticed another large coincidence associated with the date 13.11.2015 (it was the day when I (most probably) heard about Tesla's 3, 6, 9 first time in my life).
Numbers formed by last two digits in that date are 13, 11 and 15. These numbers sorted ascendingly or descendingly will form an arithmetical sequence: 11, 13, 15 or 15, 13, 11. Sum of first digits in that sequences is 3 (1+1+1) and sum of second digits is 9 (1+3+5). The difference between sum of second digits and sum of first digits is 6 ((1+3+5)-(1+1+1)=9-3=6). First digits form constant arithmetic sequence (1, 1, 1) and second digits form another arithmetic sequence (1, 3, 5 or 5, 3, 1).
Sum of numbers forming 11, 13, 15 sequence is 39. The number 39 is formed by the smallest and the largest member of "Tesla's arithmetic sequence". Difference between larger digit in 39 and smaller digit in that number is 6. In addition, arithmetic mean of 3 and 9 is 6.
Sums of digits in 11, 13, 15 sequence are 2, 4, 6. They form arithmetic sequence in which the largest number is 6 and the smallest term is three times smaller than the largest.

My first coincidences were associated with cementeries. On the cementery in which my maternal grandfather was buried his graves are between graves of men probably from the same locality who died 7 days before my grandfather or 7 days after. Grandfather died 13.12.2014. These two men died 6.12.2014 and 20.12.2014. These three dates are coincident with 21.7 and 3, 6, 9.
Sums of digits in these three dates together is 42 (6+1+2+2+0+1+4+1+3+1+2+2+0+1+4+2+0+1+2+2+0+1+4).
Sums of digits in numbers meaning year is 21 ((2+0+1+4)*3=7*3=21). There are three numbers 2014 in these three dates together. In addition, from the number meaning date a geometrical sequence with sum 7 can be formed (1, 2, 4) and an arithmetic sequence with sum 3 can also be formed (0, 1, 2).
Sum of digits in numbers meaning day and month in these three dates together is 21! 6+1+2+1+3+1+2+2+0+1+2
Sum of numbers meaning month in these three dates is 12*3 -> 36. 3+6=9.

It is the only such a date in the entire century!

It was about 27.9.2018. I made an error, I am not infallible. There is another so coincident date in 21st century - 18.9.2027. In the case of that date the arithmetical sequence 9, 18, 27 also can be separated.

Ascending geometrical sequence ending at 21 and 42 has an interesting property. It starts on number 10,5. Sum of numbers 10,5, 21, 42 is 73,5. The number 73,5 is formed by three digits which sorted ascendingly form an arithmetical sequence. It is unique arithmetic sequence - all its members are additive prime numbers (3, 5, 7) and the common difference (2) is also an additive prime number. In addition, number 357 is divisible by 21. 357=21*17.

I experienced some football coincidences in my life. Some were associated with "Mil-" part of the words, (sur)names, some with Iceland, Ireland and Scotland.

I found interesting topic in the Internet: https://www.reddit.com/r/Paranormal/com … ncidences/
Author of it writes:

For the last 3 years I have had endless amounts of coincidences, sometimes as many as 15-20 a day. The most common form is a word I am thinking or reading matching up with someone saying it on TV or in music. I have had many distinctive times where I am texting and the word I am actively typing is said at the same time or within 1 or 2 seconds max. I have been able to point it out on many occasions to people who I am with at the time. By no means has it caused me any harm but it does mess with my head a fair amount. Three years ago I had a seizure and was diagnosed with epilepsy at the age of 28. I have only had the one seizure in my life and these coincidences have only started happening since. The only trigger I have noticed that increase the incidences is stress. If anyone has had similar events it would be nice to have someone else to talk to who can relate a bit.

For me it does not look as the result of mere mathematical chance or symptom of schizophrenia or schizotypal disorder, but like genuine supernatural phenomenon. 15-20 coincidences per day is really much - before the onset of my multiple coincidences I had only about one per six months or maybe even year.

28.4.2015 might be the best date for receiving F21, F42.2, F84.5 combo in the entire time of ICD-10.
28 is 21+7.
28 is divisible by 4 and the result is 7.
Digits from 28 and 4 sorted ascendingly form a geometrical sequence with the sum 21-7 (14).

12, 24, 48. Members of that sequence divided by sum of digits in them form a constant geometrical and arithmetical sequence with sum 12 and term 4:
12:(1+2)=12:3=4
24:(2+4)=24:6=4
48:(4+8)=48:12=4
Arithmetic mean of that sequence is of course 4.

12 and 4 is somewhat interesting pair of numbers:
(1+2)*4=3*4=12 (absolute value of 12 is, of course, 12)
(1-2)*4=(-1)*4=-4 (absolute value of -4 is 4)
(1*2)*4=2*4=8 (arithmetic mean of 12 and 4)
(1:2)*4=0,5*4=2
Sum of 12 and -4 is 8 and it is arithmetic mean of numbers 12 and 4.
Sum of absolute values of 12 and -4 is 16 and is the same as sum of 12 and 4.

6.12.2014, 13.12.2014, 20.12.2014 - numbers meaning day of month in these dates form an arithmetical sequence with common difference 7. There are three numbers in that sequence, difference between the largest number and the smallest is 14 (21-7).
If these three dates would be 7.12.2014, 14.12.2014, 21.12.2014, then coincidence with 3, 6, 9 might be weaker. Sum of digits in numbers meaning days would be 15, not 12, and sum of digits meaning day and month together would be 24, not 21. I think that 6.12.2014, 13.12.2014, 20.12.2014 are more coincident with 3, 6, 9 than with 21.7. 7.12.2014, 14.12.2014, 21.12.2014 appear to be more coincident with 21.7 than with 3, 6, 9. Number 39 starts with 3 and ends with 9 and has 6 as arithmetical mean of its digits, like "Tesla's arithmetical sequence" (TAS) - 3, 6, 9. 39 is the sum of 6, 13 and 20. 6 is one of members of 6, 13, 20 arithmetical sequence and it is also a member of TAS. Product of sum of numbers in 6, 13, 20 (39) and sum of digits in that numbers (12) is 468. Digits of number 468 form an arithmetical sequence which has sum of numbers 18 and 6 as middle member or arithmetical mean - like in TAS. Product of 42 and 15 is 630, the sum of digits is 9 and digits form an arithmetical sequence with common difference 3.

I think that 7.12.2014, 14.12.2014, 21.12.2014 would be more coincident in general than existing coincidence associated with 6.12.2014, 13.12.2014, 20.12.2014. 7, 14, 21 gives large coincidence with 3, 6, 9. But the coincidence with 13.11.2015 (the day on which I heard about Tesla's 3, 6, 9, probably first time in my life), where an arithmetical sequence associated with two last digits in the numbers of the date would disappear if three coincident dates would be 7.12.2014, 14.12.2014, 21.12.2014, also the date of grandfather's death would not be coincident in its two last digits meaning day, month and year when it would be 14.12.2014, not 13.12.2014. Biggest Tesla's coincidence in my life was associated with two last digits of the numbers meaning day, month and year in the date 18.12.2015. There are only two dates so coincident in 21st century (and any other century). Next so coincident date would be 15.12.2018. Chance for such a coincidence is about 1:18300.

Three arithmetical sequences with sum of numbers 39 and sum of digits 12 were coincident:
- 12, 13, 14 in the date of grandfather's death,
- 6, 13, 20 in the dates of deaths of three men (probably from the same locality) whose graves are side by side on one cementery [I probably thought about the word "tomb" a moment earlier and I found such a phrase in one of pages when I looked for translation of Polish phrase "obok siebie": Henry and I sleeping side by side like figures on tombs.]
- 11, 13, 15 - the date when I, probably listening or watching an audition on 84th channel of satellite TV, heard about Tesla's 3, 6, 9.

From common differences (CDs) of arithmetical sequences: 6, 13, 20 (CD 7); 11, 13, 15 (CD 2); 12, 13, 14 (CD 1) phrase "21 7" can be formed.

Sum of products of digits forming three sequences mentioned earlier is 39:
- 6*1*3*2*0=0
- 1*1*1*3*1*5=1*3*5=15
- 1*2*1*3*1*4=2*3*4=24
0+24+15=39.
39 is the sum of any of sequences mentioned earlier.

84, 42, 21 and the sequence formed by reading its backwards: 12, 24, 48 have interesting feature associated with results of division of its members by sum of digits in these members:
84:(8+4)=84:12=7
42:(4+2)=42:6=7
21:(2+1)=21:3=7
7+7+7=21. Sum of that constant geometrical and arithmetical sequence is 21, single member or arithmetical mean of the members of the sequence is 7. So we have 21 and 7.
12:(1+2)=12:3=4
24:(2+4)=24:6=4
48:(4+8)=48:12=4
4+4+4=12. Sum of that constant geometrical and arithmetical sequence is 12, single member or arithmetical mean of the members of the sequence is 4. So we have 12 and 4.
Both pairs of numbers (21 7 and 12 4) have arithmetical mean which is the product of digits forming that numbers:
(21+7):2=28:2=14, 2*1*7=14;
(12+4):2=16:2=8; 1*2*4=8.
In addition:
(2+1)*7=3*7=21;
(1+2)*4=3*4=12.
21 is 12 read backwards, 12 is 21 read backwards.

ASes 11, 13, 15; 12, 13, 14 read backwards form another ASes - 51, 31, 11; 41, 31, 21. Sums of numbers in that ASes are 93.
"Original" ASes have sums of numbers 39.

In the case of ASes with three numbers and 14 as AM the phenomenon of "mirror numbers" as sum of numbers forming the sequences is not present:
10, 14, 18. Sum 42. Backwards: 81, 41, 01. Sum 123.
11, 14, 17. Sum 42. Backwards: 71, 41, 11. Sum 123.
12, 14, 16. Sum 42. Backwards: 61, 41, 21. Sum 123.
13, 14, 15. Sum 42. Backwards: 51, 41, 31. Sum 123.
14, 14, 14. Sum 42. Backwards: 41, 41, 41. Sum 123.
Difference between 123 and 42 is 81 (9*9, 3*3*3*3). Sum of digits in sums of three numbers forming such an AS is 6.

During encounter mentioned earlier there was text consisting of two letters repeated many times present on the screen. These two letters were two first letters of impolite word meaning that part of body in which something resembling big W is located!

In addition, there was certain thing, item (let's name it V) which could be found during that encounter. 18.10.2018 I typed "V w (fragment of that region of body)" ("V in the (fragment of that region of body)") in Google translator. There was translation from Polish to English. Next I typed a transliteration of Russian term meaning a creature from Russian game mentioned earlier in Google. There were 23 results. In the third link (its description) there was present Polish word for V. Next I found the English word for V in Polish page about something which was some form of English language. Next day, 19.10.2018, new coincidence with V happened. I thought about V from the Russian game in a large shop and few moments later I heard two "advertisements" of two certain Vs! Today, 21.10.2018, I noticed that two first letters of Polish term for V and three last letters of that term form a word which is a part of the Polish name of the monsters which I saw in Russian game 14.10.2018. Fight with that monsters was observed in next film or films with playing of that game after the film with "Big W" encounter.
