go to a newage store, the kind of stores that have magik books, insense, crystals and all that groovy witchcraft stuff. i went to a local store called "mystic goddess" and rented a video tape on remote viewing AND astral projection (same tape). the guy explained the difference between the two and then set you up to watch the tape for about 30 minutes of psychedelic lava lamp like patterns while he talked you through with breathing instructions and visualizations. all the while a metronome ticking sound would start out at a certain rate and settle at a certain resonace that is supposed to bring you brain into the alpha state (according to the fella who made the tape). the best remote viewing i did was when i tried ot go to mars and kept getting images of guys holding an auto parts store instead (throwing stuff around also and just being real all around axxholes).
only to find an article in the local paper a few days later of a rash of auto part store holdups.
my trip to mars was boring and all i saw was an underground facility that was many levels deep. no newpaper articles to varifiy what i saw that trip if you know what i mean.
i had trouble astral projecting, i felt the "looseness" of my astral body, but couldn't leave my physical body. (probably because i have a fear of not being able to come back once i leave.)
