Im not really Eli Whitney....I'm just a phoney. So because you did a post about it already it means that this is not possible? Did you actually research blind people on hallucinagens? And if so I apologize in advance.
read it for yourself: http://psych.ucsc.edu/dreams/Library/kerr_2004.html basically, that blind people can't and don't see in their dreams unless they were made blind at the age of 5 minimum
Does it say anything about psychedelics? It looks like it just talks about dreams. And how reliable is this site?
I would say the University of California's Psychology Department is pretty reliable... and no, but I also linked to another person asking this, where multiple people explained why it wouldn't work and one even talked about when his blind brother was on acid.
