Symbolic number 3

[Mortimer]

In Army hospital in Belgrade a Serbian Nationalist told me that fans of the football club "Rad" are Neo-Nazis and that they always are in groups of "3". The Serbian Chetnik Trojka was a unit of 3 men, who executed enemies on the order of Draza Mihajlovic. The 3 Finger Salute is the Symbol of Serbian Patriotism.

Ok, that being said a little about the backstory. In 2005 and 2006 I was heavily paranoid and psychotic. It was really like in a bad horror movie but that I was the main actor in it. Ok now the symbolic number 3 occured to me in a parnormal and paranoid way.

Examples:

I was at McDonalds, I was psychotic, I made a order and the burger flipper said "Do you want 3 Burgers" that striked as me paranormal
I was called by the bank accountant, he said do you want a bank account, and if so come over to our bank for a appointment I said when and he said "At 3 o'clock". That striked fear in me and I didnt go there.

So it happened regulary, in that time period that the number 3 came into my head as symbolic and parnormal or supernatural.

I mentioned the backstory, because I remembered the nationalist when I was psychotic and that he said "3". So I connected that a bit. I dont know if for any good reason though.

Anyone has any feedback or comments or ideas? Did you had similar experiences?
