yep. there's plenty of evidence around to prove it, i'm sure the Mods will be able to point you to some... get to work Mods
in the meantime, consider, would the US military have spent so much time/effort in developing remote viewing programmes, if the benefits were simply fabrications of the mind?

from my own experiences, i've had validation thru connecting with friend's consciousness when they're on the other side of the world, and shared experiences with numerous friends, nearby, and in other countries at the time.
how could we all be in each other's brains, having the same experience, at the same time?...

and when you get the validation you're looking for, you'll then have to reconsider your opinion regarding "where" consciousness resides... cos it's not in the brain.
sure the brain allows us to experience physical senses and reality and all that goes with it, but consciousness doesn't end with the brain.
and when you get your head round that, , you'll have no choice but to start considering and understanding the true nature of reality... and that's when things really get fun!!

the rabbit hole is bottomless, it seems.
enjoy the trip...
