Exactly my thoughts, guess sometimes our brains can't even comprehend that we exist, it's just unreal, even unreal to believe that the moment we die, we'd just vanish into thin air, it's hard for me to believe that one part.

I agree on the memory fabricating, it's been proven that you can put memories into other people, I've seen a documental about it, but not right recall the name. I've quite a few other memories that I can easily distinguise if they are fabricated or unreal, some coming from dreams I've had since I was a child.
