ZeroShadow - the link you gave made me laugh. Who are these people? The guy who said astral projection was a 'hallucination' was worse of all. Think about it - Thousands of people astral project a day, all feeling exactly the same sensations and having similar experiences. Hallucinations simply don't work in such a way. A hallucination is a sensory experience in which a person can see, hear, smell, taste, or feel something that isn’t there.
They are random mind renderings made solely by one's own imagination. Anyone who has researched astral projection or astrally projected themselves will know astral projection is simply too dynamic and external an experience to be associated with the mind. The rest of them are the same. They need only do a little more research - analyze some statistics, interview experienced projectors - to know they are wrong. It seems they are being skeptical for the sake of it - I recommend you don't read what they have to say.
moomooman - astral projection and OBEs are the same thing.
Spikester - I have projected on many occasions. When I project, I get out of bed and immediately pull my finger and pinch myself to make sure I am fully conscious. I look around the room and gather my surroundings. It takes a few seconds to register that I am astral projecting.
Sometimes I walk around my house, other times I simply fly away. In the astral I am quite heavy so I jump about as high as a two story house and fly for a little bit before being pulled back down. I repeat this over and over. So my flying method is sort of like bouncing along on the moon. Only sometimes, if I focus very hard, can I glide like a bird.
There are so many memories so I may as well share my last projection with you.
I flew out of my house and landed on a front lawn a few blocks away. I walked inside the house and met a dark-haired woman. She could see me and talk to me subliminally, so obviously she was an entity from the astral plane. I talked to her about astral travel and told her about how I could go through walls. She seemed very interested. To prove it, I stuck my hand inside the wall in front of us.
I saw a flight of stairs and walked to the second story of the house. Deserted. When I went back downstairs, the woman was gone. I went and lay underneath the stairs for a while, waiting for her to return.
She didn't, so I flew outside again. Back on the front lawn, I gently glided over the grass, about 1 foot from the ground. It was lovely. I knew in order to keep the OBE going I needed to have a purpose, but I couldn't think of one. As I floated, I began to feel myself fading.
I woke up to my whole body pulsing with intense vibrations.
It's a boring one, but I guess it's something. If you're still interested, I'll post the next projection I have.

And no, I have never run into trouble. The entities I've met have been very friendly.
