Rayge Your wrong. Your friends are mentally retarded.
It's the multidimensional travel accessible by the subconscious stream of locking trance states, or meditation if you wanna call it; its the ancient principle and reason meditation was idealized. Which brings up about 1000000 other topics -_- but anyways, it's a subconscious trance right, why are the brainwaves singular when heightened sensations and thoughts are being created; strange that on a a device simialar to that used in EEG's and EKG's it wouldn't pick up the largest of electrical stimulations.
It's like you thinking about a different brain.
