I'm a new user and I just saw a thread about lucid dreams but it was close. I'm a practicioner of the astral projection and I've had many experiences. Sme were good and some were bad. I will be happy to share my techniques and exercises with anyone who ask me. And yes you can use weed to get out of your physical body. It is not necessary but it helps a lot in the relaxation phase, just don't fall asleep.
