Topic: Very good OBE site
There are many sites dealing with OBEs and lucid dreaming out there in the net, but I find this one very, very good:
What I like most are the models/theories behind the OBE phenomen. I recomend reading the articles at the top page even if you are not interessted in OBEs itself but interessted in the different states of the body and mind.
Take a look at:
