Alright, this is how you can do it quickly and without too much hassle. Go to I-tunes, search for "Kelly Howell - Music & Delta Brain Wave Therapy". There are two tracks, about 30 minutes long. You listen to them with head phones and they use a lot of low pitch sounds and music to induce a waking dream state. I'm not saying you're walking around in the Matrix, but it's really soothing and if you take deep breaths after about ten minutes your brain sorta detaches.
If you do the guided, this woman's voice will take you through this weird walk along a beach and channeling all the negative energy, etc. If you do the unguided...your brain detaches and then it's just you and your subconscious.
I got bored with the guided and started doing the unguided and it was proving to be pretty weird. Lots of walking in dark forests and floating in outer space. Eventually it got to a point where there weren't even stars, I was just floating, and suddenly this old man's face just appeared. He started screaming at me that I was seriously in the wrong place and to get the hell out of there.
Uh, after that I spent about a year having disturbing stuff from my childhood come to the surface in a variety of ways. It wasn't pleasant, but I guess I unloaded a lot of baggage.
