Some of you might have already seen this, but check out this vid, read the instructions and do what it says, and then take a look around your room. (Make sure you full screen it) [ame=http://www.youtube.com/watch?v=vzSRVgF501M]Natural Hallucinogen - YouTube[/ame]
If you want to actually hallucinate naturally. Cut ping pong balls in half and cover your eyes with them. Set your radio/tv to just get static/white noise. Then shine a red light onto your eyes. Lie down and enjoy the trip.
Lol if you block all signals to your brain you trip out basically. It's #4 on this list. http://www.cracked.com/article/127_5-ways-to-hack-your-brain-into-awesomeness/
What actually happens when you do that? Is it *actually* similar to a hallucinogen trip? (sensory deprivation that is) I mean this video is cool and all, but it's not really comparable
I've never done it but I've looked around trying to find out if it works. From what I've found it's just a weak version of sensory deprivation. But sensory deprivation does cause auditory and visual hallucinations. Some people even compare it to LSD.
