lets push aside the fact that its a normal feeling all human beings have at some point in their lives and speculate on the supernatural. (one of many
ironic traits all humans possess, not ironically.)
its normal not the matrix (ironically, and idea of the matrix is another human ability to
create ways to disassociate...)
then again i could be wrong (not ironically)
at some point in the life of all humans, they have this feeling. ( i cant prove this, dont need to; even the most hardcore atheist have had a
moment where they 'believe', even if briefly. physiologically, its normal)
I've been experiencing that feeling since I was a kid, its really odd because when it happens, I feels l like I'm literally in an alien world although
I know what everything is, for the most part. Even my own body looks and feels alien to me. At least, that's the best way I could describe it.
It's a Subliminal Suggestion to your mind. If you're weak and fall into the assumption of what you've been told all your life then yes, everything you
dream and experience here will feel like it's real. It doesn't really matter if you do or don't it's still all crap and not actual reality, even
though you perceive it as such.
