Yeah pyschonauts are astronauts of consciousness. They basically explore altered states of consciousness and explore the experiences they get. Apparently this amounts to understanding something in some way. I think it is an interesting experimentation people do on themselves. Some people actually deliberately structure their environment so that they will easily be able to tell when they are in a dream, thus making dreams lucid. I wonder if some scientist will come up with a BCI that causes all or most dreams to become lucid so people can play around in their minds as much as they want. That in a sense, will bring that third of our lives that is spent sleeping. The only thing is the idea of taking drugs as a means to accessing some truth seems kind of dumb. When you get to a point where your definition of reality makes it so that taking hallucinogenic drugs is still reality, one may ask if you have become self-deluded.Yeah, some people love it so much, I find it quite scary. It's like eating various food endlessly because "it tastes good". Physical things you put in your body can have long term physical effects. The same goes for drugs, and long term physical effects on the brain. It's by far the most powerful organ, and everything is very finely tuned. I learned that the hard way. To be put into a state where you question your own reality, and have constant lurking 'bad' feelings like paranoia, fear etc. It's horrible. Playing with the brain is dangerous. I'm amazed some people can continue doing it for 'fun' for so long.
An extreme inversion of common sense makes common sense seem like a delusion. So everyone else is delusional except for you, that person taking drugs. Interesting how we have the capacity for such thoughts.
