Good article, solstice. I've projected a couple of times, although never intentionally and in what form I am not sure (more on that later). First, however, allow me to point out that Monroe's hypothesis that the second body consists of antimatter is rediculous. As far as I remember, although correct me if I'm wrong, unless Monroe was projecting in a near perfect vacuum, his 'antimatter' body and the closest similar amount of nearby matter (aka, his physical body) would cancel out in a none-to-small poof, leaving one less projector.
I've tried methods similar to yours, although probably not often enough for them to have any noticeable effect. When I have projected, always by accident, I would wake up in sleep paralysis and would will myself out. The first time this was incredibly difficult, with my entire 'second body' paralyzed as well, albeit able to float about. The second time it was much easier, with a full range of movement and vision. Neither involved any vibrations or noises. While I could not pass through solid matter either time, I could somehow phase myself through cracks around the door on the second occasion to appear on the other side. Both experiences started out very destinct and memorable with few, if any, discrepencies between what I saw and what was in real life. However, the first time I bumped into the door five times, 'waking' back in my body each time, before the experience devolved into a dreamlike state, with numerous inconsistencies (door being open instead of closed, light being on, a new room with odd people in it, and people I knew seeing me and acting different than they would). Similarly, the second time started out normal (although I swear my cat reacted as if he saw me) until I went downstairs and phased through the front door, at which point the experience became rather trippy for a few minutes and then devolved into a short and quickly forgotten dream. So, I wonder, what kind of projection was it? Ethereal, Astral, or first one and then the other? Also, though this may not be the topic for it, what would be the difference between an astral projection and a lucid dream, since I heard that dreams are basically subconsious astral projections anyway?
EDIT: Whoops! After posting this I went to the Projection boards and saw your article explaining psychic projections and thereby practically answering my question. I'll leave the second paragraph up here anyway, if nobody objects, and feel free to have a shot at it if you're bored, seeing as how its a more exact real life example. If it serves no purpose, kill it.
