There was this blog on Tumblr that posted something about if you have a birthmark, it's where you were injured in your past life and died.
I don't really believe that, but it's interesting.
A big thing people find interesting is Deja Vu. It's mysterious and a sign that we're in a simulation or whatever people think.
What I heard is that it's just your brain misfiring.
Like you haven't done this before, your brain just messes up and you think you've done it before.
I used to get Deja Vu all the time. I get it occasionally now, but it was always very unsettling to me.
I'm the type of person that would find it cool normally but I didn't like it.
It made me feel uneasy and scared xD
