(Sorry, last post is incomplete)

I may wonder why the coincidences happened in my life. They started in 2014. Earlier I practically did not experience that sort of phenomena. Many people voted that my coincidences are results of mere mathematical chance - maybe they are, although the probability of it may looks relatively low.

Now new coincidences are quite rare. When I had some of my first coincidences 22.09.2014, I was excited, agitated and severely stimming, which was soemtimes loud. Earlier coincidences were interesting, although they were not associated with F21, F42.2 and F84.5 or 28.4.2015 or 24.6.2016 or 33, 42, 51 or 3, 6, 9 or 21.7.

There is interesting phenomenon associated with prime numbers and some of arithmetical sequences which have sum of digits 18, number of terms 3 and middle member 24 or 42:
- 11, 24, 37 (common difference 13)
- 11, 42, 73 (common difference 31)
- 17, 24, 31 (common difference 7)
- 13, 42, 71 (common difference 29)
All extreme members of these four arithmetical sequences are prime numbers (11, 37, 73, 17, 31, 13, 71)!
All four common differences are prime numbers (13, 31, 7, 29)! In extreme members of these four sequences only three digits are present: 1, 3, 7. Numbers 1, 3, 7 are not composite. Their product is... 21, one of factors is 7.

This is not the only phenomenon associated with these sequences and prime numbers. When we sort digits forming one of these four sequences ascendingly, we will receive 1, 1, 2, 3, 4, 7. When we produce three two-digit numbers from these digits, we will receive 11, 23, 47.
23-11=12.
47-23=24.
The difference between second and first number in the sequence is 12 and the difference between third and second numbers is 24. Let's add 12 to 24 and add the sum of 12 and 24 to third member of the 11, 23, 47 sequence.
12+24=36.
47+36=83. 
So we have four-membered sequence: 11, 23, 47, 83. Let's add 36+12 to 83 to produce fifth member:
36+12=48
48+83=131
Let's add 48+12 to 131 to produce sixth member:
48+12=60
131+60=191
Let's add 60+12 to 191 to produce seventh member:
60+12=72
191+72=263
We received seven-membered sequence: 11, 23, 47, 83, 131, 191, 263.
Eighth member is 263+84=347. Seven first members of the sequence are additive prime numbers, it is probably the smallest such a sequence of at least seven additive prime numbers (eighth member is a prime number, but not an additive prime number).
1+1=2
2+3=5
4+7=11
8+3=11
1+3+1=5
1+9+1=11
2+6+3=11

I noticed something interesting in sums of digits in the date 28.4.2015. If we count the digits which are present here one times each, we will recieve 20 - 2+8+4+0+1+5. Second number 2 was not counted. If we add all digits which are in the date 28.4.2015, including repetitions, we will receive 2+8+4+2+0+1+5 = 22. We received two numbers: 20 and 22.
Arithmetical mean of these numbers is 21 ((20+22):2=21).
Sum of the numbers 20 and 22 is 42.
Difference of squares of these numbers is (22*22)-(20*20)=484-400=84.

The sum of digits meaning day and month in the date 28.4.2015 is 14. Digits forming numbers 28 and 4 sorted ascendingly or descendingly form geometrical sequence. 14 is arithmetical mean of numbers 21 and 7 and difference of 21 and 7.

In the number meaning year in date 28.4.2015 there are the same digits as in birth weight written in my health certificate (2150 g).

I also noticed that the sum of numbers 77 and 7 is 84. Sum of digits in the phrase "77+7" is 21. In the phrase "77.7" there is only one sort of digits - 7.

I was diagnosed with schizophrenia (F20 in ICD-10) only in some weeks of the first half of 2016 year. Earlier and later I was diagnosed with schizotypal disorder (F21 in OCD-10). I had some "paranoid" fears (for example that other people may want to poison me or kill me) since being about 16 years old. I do not remember having that symptom when I was younger than about 16 years old. But I was diagnosed with F21 in 2015, not earlier. Earlier I received diagnoses of AS and OCD (since 2008-2009). Large number of coincidences occurred quite suddenly in autumn 2014. I had a visit with my former psychiatrist 21.10.2014 and I was still not diagnosed with schizotypal disorder despite having coincidences since about one month at that time. Diagnosis of F21 appeared first time during next visit, 27.1.2015.

Hallucinations were (almost) not present in my life. I remember about 15 cases of hearing simple voices when I was about 20 years old and two flashes when I was about 17-18. I had not Schneider's schizophrenia symptoms.

I am quite probably the only man in the history in whose life two sequences: one arithmetical (33, 42, 51) and one geometrical (21, 42, 84) are important. These two sequences have pretty peculiar properties and I noticed it. I think that it is much larger chance to be a millionnaire than to have a special interest in two peculiar mathematical sequences.

The three-numbered sequence which is arithmetical and starts with 21 and 42 is 21, 42, 63.
Sums of digits in that sequence are: 3, 6, 9.
From first digits of the numbers forming 21, 42, 63 the number 246 can be formed.
From second digits of numbers forming 21, 42, 63 the number 123 can be formed.
Sum of numbers 246 and 123 is 369. 3, 6, 9 again!
The sum of digits in 21, 42, 63 is 18, like the sum of numbers or digits in 3, 6, 9.
Sum of numbers forming sequence 21, 42, 63 is 126 - the same as sum of numbers forming sequence 33, 42, 51.
Quotient of sum of the numbers forming sequence 21, 42, 63 and the sum of digits forming that sequence is 7:
(21+42+63)2+1+4+2+6+3)=126:18=7

The sequence formed by reading the sequence 21, 42, 63 backwards is 36, 24, 12.
Sums of digits in that sequence are: 9, 6, 3.
When we make that sequence ascending instead of descending, we will receive 12, 24, 36.
Sums of digits in that sequence are: 3, 6, 9.
Sum of numbers forming sequence 12, 24, 36 is 72 - the same as the sum of numbers of the sequence formed by reading the sequence 33, 42, 51 backwards - 15, 24, 33.
Quotient of sum of the numbers forming sequence 12, 24, 36 and the sum of digits forming that sequence is 4:
(12+24+36)1+2+2+4+3+6)=72:18=4

The three-numbered sequence which is arithmetical and ends with 42 and 84 is 0, 42, 84.
Sum of digits forming that sequence is 18 and the sums of digits in the numbers forming that sequence form an arithmetic sequence (0, 6, 12):
0=0
4+2=6
8+4=12
Sum of numbers forming that sequence is 126 and sum of digits forming 0, 42, 84 is 18. 126:18=7.

The sequence formed by reading the sequence 0, 42, 84 backwards is 48, 24, 0. It is an arithmetical sequence.
Sums of digits in 48, 24, 0 form an arithmetical sequence (12, 6, 0).
Sum of numbers forming 48, 24, 0 is 72 and the sum of digits forming that sequence is 18. 72:18=4.

16.4.2018 - coincident date. 4 and 16 are second and fourth powers of 2. From that date we can separate five numbers which are natural powers of 2:
- 16 is 2^4
- 4 is 2^2
- 2 is 2^1
- 1 is 2^0
- 8 is 2^3
These numbers formed ascendingly or descendingly form a five-numbered geometrical sequence! 1, 2, 4, 8, 16.
Interesting arithmetical sequences can be formed from 16.4.2018:
- 0, 2, 4, 6, 8 (may have 10 as sixth term when we write the date as 16.04.2018)
- 0, 4, 8, 12, 16 ("engages" all digits in the date)
- 0, 6, 12, 18
- 0, 8, 16, 24

Weaker coincidences are present in the case of the date 4.6.2018. The sum of digits is 21. 21 can be formed (from digits in number meaning year). If we remain only last digits of th date, we will receive 4, 6, 8 - "Tesla-like arithmetical sequence".

These coincidences may be vieved as the proof of existence of supernatural beings. They are numerous. It is not one coincidence or two. It is complicated "network". Someone might consider them as extensive delusional system. If I would be diagnosed with (paranoid) schizophrenia (F20(.0)) instead of schizotypal disorder (F21), there would be no "miraculous" geometrical sequence 84, 42, 21. In Polish AS forum there was a person who write above well above 100 posts and had the login F21 (not F20 or F22). That person formed account in 2015, the year in which I received F21 diagnosis first time. The combo F84.5, F42.2, F21 was written in many "excerpts" from my ambulatory visits with psychiatrists, first time these 3 diagnoses appeared together (as only 3 diagnoses which I got) 28.4.2015. The date is strongly coincident with three diagnostic codes.

I noticed something interesting about date 28.4.2015. It was 118th day in 2015 year. At 2015 there was also one another date composed by the same digits and with the same sum of numbers - 24.8.2015. Between 28.4.2015 and 24.8.2015 there were 118 days and 24.8.2015 was 236th day in 2015 year.

Next dates which have at least two digits "2" and at least one digit "1", "4", "5" and "8" and have the number meaning day divisible by the number meaning month are 28.4.2051, 24.8.2051, 14.2.2058, 12.4.2058. Digits forming numbers meaning day and month sorted ascendingly or descendingly will form geometrical sequences with sums 14 or 7: 2, 4, 8 (8, 4, 2) and 1, 2, 4 (4, 2, 1).

https://wrongplanet.net/forums/viewtopi … 5#p8015996 - today I posted in "counting topic" on WP forum first time since quite much time. The number which I typed was coincident. It was 42,714. From that number 42, 7, 14 (three numbers divisible by 7) can be formed. 42 is the middle term of my two very coincident sequences - arithmetical 33, 42, 51 and geometrical 84, 42, 21. 42 is (21:7)*(21-7). 14 is 21-7 (the difference of 21 and 7) or (21+7):2 (arithmetical mean of 21 and 7).

Let's sum up informations about 21.7 coincidence - part 1:
1. My first ambulatory visit with the psychiatrist (my former one) after onset of coincidences occurred 21.10.2014 and was postponed from 07.10.2014. 21st and 7th day of the month.
- the number meaning month is the sum of digits in numbers 21 and 7 (2+1+7=10),
- sum of digits in number meaning year is 7 (2+0+1+4=7),
- there are 2 weeks (14 days) between initial and later term of the visit,
* numbers 2 and 14 can be separated from the number meaning year (2014),
* product of numbers 2 and 14 is 28, which is the sum of 21 and 7,
- from the number meaning year a geometrical sequence with sum of numbers 7 can be formed: 1, 2, 4,
- from the number meaning year an arithmetical sequence with sum of numbers 3 (21:7) can be formed: 0, 1, 2.
2. My second visit with a psychiatrist after beginning of the coincidences occurred 27.1.2015, the sum of numbers meaning day and month is 28 (21+7), numbers meaning day and month are formed by the same digits as 21 and 7.
3. My first visit during which I received diagnoses F21, F42.2, F84.5 at the same time together (and only them) occurred 28.4.2015.
- the number meaning day is the sum of numbers 21 and 7,
- the quotient of number meaning day and number meaning month is 7 (28:4),
- from the digits of numbers meaning day and month a geometrical sequence can be formed (2, 4, 8 ), its sum is 14 (21-7 or arithmetic mean of 21 and 7)
4. Sum of numbers in the sequence 21, 42, 84 is 147 (21*7).
5. Sums of digits in numbers 21, 42, 84 form geometrical sequence with sum 21 (3, 6, 12) and differences of digits form geometrical sequence with sum 7 (1, 2, 4).
6. Sum of digits in first part of codes F84.5, F42.2, F21 is 21 (8+4+4+2+2+1=21) and in second parts sum of digits is 7 (5+2).
