There is much discussion about the different types of projections. I believe they can be understood by the degree of active versus passive techniques involved with the particular type of projection. Understanding this should help clear up a lot of the disagreements.
dreams = passive induction
astral projection = passive induction
etheric projection = active induction
mind-split out of body experience = active induction
phasing = passive induction
meditation = passive induction
hypnosis = passive induction
Passive techniques focus on the intent and desire of the projectionist, while the active techniques focus on will intensity.
Either you are focusing on the active or you are focusing on the passive. They are opposites to each other.
