This vid reminds me of sci-fi films from the ’50s. I’m in no way supporting drug use … but the description by a most unlikely subject is rather enchanting.
If I want to explore my consciousness I try intensive meditation with sleep deprivation. I don’t know think it’s the same state but it’s a good state that doesn’t just change perception can change actuality. When I meditate intensely the world flows more with my will and inner being seem to affect outer reality. I can’t prove this connection and any anecdote can be put down to coincidence.
I don’t do that kind of meditation now or indeed any meditation on a disciplined basis. It’s hard work and I’ve become incredibly lazy. Nevertheless I would recommend meditation above experimentation with drugs for people who want to expand or explore consciousness.
