"Hacking" Your Brain

"Brain Hacks" - About a half-dozen ways to fool your brain, essentially causing your self to hallucinate - legally. A few of the "hacks" include making yourself feel pain when you watch someone hit a rubber hand with a hammer (as though it were your own hand), or making it feel like your nose is a foot long are two examples of the weirdness available to you without the chance of involving "the man".
