Dude, some people don't believe that we've been to the moon. Most people have had experiences that they can not explain and they alway manage to either ignore it as an anomoly of the brain, or completely forget about it.
Some skepticism is totally beyond me. There are 10 to the 24th power stars in the KNOWN (nevermind what we can't see) and we are the only life
? Nearly every culture (regardless of race, religion, and geographical separation) has had OBE or describe something similar yet it is some kind of mass illusion or brain abnormality? Sorry but that is just too improbable for me.
cut to the chase and be skeptical about the reality of "reality" and the validity of perception. If everything is a really elaborate illusion, then the only thing left to do is enjoy the ride be it dreamtime, astral phenomenon or complete insanity.
