I noticed "mysterious 21.7 coincidence" in my life.
7.10.2014 a visit with my former psychiatrist was planned, but it was postponed to 21.10.2014 (that day the visit took place in fact).
Next visits with that doctor took place at: 27.1.2015, 28.4.2015, 21.7.2015 and 8.12.2015.
I received interesting diagnoses at 28.4.2015. F84.5 (Asperger's syndrome), F42.2 (mixed obsessive-compulsive disorder), F21 (schizotypy). Look at the numbers - there are geometric sequences in them and associations with numbers: 7 and 21...
84.5
42.2
21
Numbers: 21, 42, 84 form a geometric sequence:
21 = 21*2^0 = 21*1 = 21
42 = 21*2^1 = 21*2 = 42
84 = 21*2^2 = 21*4 = 84
Sums of digits in numbers: 21, 42, 84 also form a geometric sequence:
2+1 = 3 = 3*2^0 = 3*1 = 3
4+2 = 6 = 3*2^1 = 3*2 = 6
8+4 = 12 = 3*2^2 = 3*4 = 12
Sum of the numbers: 3, 6, 12 is 21, and their arithmetical mean is 7!
First digits from numbers: 21, 42, 84 also form a geometric sequence:
2 = 2*2^0 = 2*1 = 2
4 = 2*2^1 = 2*2 = 4
8 = 2*2^2 = 2*4 = 8
Second digits from numbers: 21, 42, 84 also form a geometric sequence:
1 = 1*2^0 = 1*1 = 1
2 = 1*2^1 = 1*2 = 2
4 = 1*2^2 = 1*4 = 4
Sum of numbers: 21, 42, 84 is 147 which is 21*7!
Sum of numbers: 2, 4, 8 is 14, which is 7*2.
Sum of numbers: 1, 2, 4 is 7, which is 7*1.
Sum of the sums of digits in three numbers: 21, 42, 84 is 21 is 21 (2 + 1 + 4 + 2 + 8 + 4 = 3 + 6 + 12 = 21)!
Put the sum of first digits in numbers: 21, 42, 84 (sum of 2, 4, 8 is 14) before the sum of second digits in numbers: 21, 42, 84 (sum of 1, 2, 4 is 7) and you will receive 14 and 7 ---> 147 ---> 147, which is the sum of 21, 42, 84!
Sum of digits before "." in my diagnoses from 28.4.2015: 2 + 1 + 4 + 2 + 8 + 4 = 21
Sum of digits after "." in my diagnoses from 28.4.2015: 2 + 5 = 7
So it forms "<21.7>"! Date of my next "ambulatory" visit was 21.7.2015. My previous (28.4.2015 is named as the date of "present" "ambulatory" visit here) "ambulatory" visit took place at 27.1.2015.
21+7=27+1=28
Write these three dates in chronological order, latter below earlier...
27.1.2015
28.4.2015
21.7.2015
In the "row" for month "147" is formed, 147 is the sum of 21, 42, 84!
I watched an audition (it was not so clever audition, however because of its content, I disagree strongly with its "beliefs" and ideas, which are for me "stupid") at 18.12.2015 (twenty-first century, fifteenth year of that century, twelfth month of that year, eighteenth day of that month), between 5 p.m. and 6 p.m. (in the time zone in my country) and I received mysterious coincidences because of it! Few weeks earlier I watched the same audition (but another topic was discussed), also between 5 p.m. and 6 p.m., at the same day of the week and at the same channel, that day the audition was about an inventor who was named as "megakook" (translation from Polish) by an Aspijka whose blog I quite often read (she wrote that that inventor would have received OCD diagnosis, if not AS diagnosis in recent time) and during that audition I heard about three numbers which form an arithmetical sequence (are three first numbers in that sequence) in which 21 is the 7th "number" of that arithmetical sequence!
