I have read Robert Monroe's first two books, which I find fantastic but very believable from a skeptical standpoint. If you haven't read them, I strongly recommend it. Can usually find them at bookstores under metaphysical or check your library.
Anyway, I practice projecting nearly every night and often during the late afternoons whenever I have the time. I use deep breathing, also counting my breaths, and then kind of a mixture of silencing my mind with some inner dialog. I usually tell myself I am relaxed, I will feel no sensations or discomfort, and will slip in to a vibrational state. If I am having a particularly stubborn time at it, I will do an entire body-relaxation routine starting with my feet and moving up. It's much like self-hypnosis and I've been wondering how well an actual self-hypnosis audio clip of myself would work? In theory I think it would work great, just haven't gotten around to trying it yet!
I've been able to induce some serious vibrations. The strongest felt as if I didn't know where my face or hands were anymore, like they were flipping around all over very fast. It was a sensation so intense I literally laughed out loud, it almost tickled like when your foot falls asleep and you nearly can't stand it but it doesn't HURT. But that doesn't happen all of the time... Anyone else experienced this?
I also want to share a few problems I've encountered.
1.> I sometimes can't stop focusing on my breathing, and it induces panic the closer I get to separation. I'm sure that my brain is freaking out in fear thinking that if I leave I'll stop breathing, so my heart rate speeds up and other assorted nonsense... it's been difficult to overcome but lots of people say that fear is the number one obstacle.
Thanks for reading guys, I hope this helps and gets some feedback!
