Today I woke up after a dream of a tall man in a black suit walking down the street. He came up to me and said hi then just magically disappeared. That was the end of the dream. I was kind of confused on what it could mean until I went outside 2 hours later to play some lacrosse. Some time later I see the same exact man walk right down the street in front of my eyes. I've never seen that man before and he looked very unusual as well. He had a deformedchin and he was wearing a black suit in spring, just casually walking down the street. Shook.
Its just an effect from your brain, some people will call science reason some other will cause that with some conspiracy shit, search on google you'll find more about it
This kind of thing is an impression reaction, in fact you don't see such person, but when you see you this person, you will see the person that you see to compare with your dream.
