With practice, this state can last forever and one can use it to practice many highly advance "meditation" techniques. This is a doorway one must learn to experience in order to become more aware of the distinction between being within the confines of the body by opposition with being outside of it. As soon as you are outside of it, even if it is only a millimetre above your eyes, your entire body is apparently paralyzed, unless you have had enough experience to feel that you aren't within the confines of the body anymore. Still, with tons of experience, it is still a bit confusing to hear that your body was actually snoring while you think you are silently observing the person getting ready to come to bed with you. LOL!!!

Namaste :)
