i want to knoe eho can seem to step out of thier body and resume life and not even know it though
i think you might be reffering to an O.B.E.
these are almost LITERATLY stepping out of your body into your non-physical worldand doing whatever you want.(this might be a bit harder in an O.B.E. as it is more realistic than lucid dreams, such as transforming, you may find it a bit more dificult, but dont believe anything is dificult in a lucid dream or O.B.E. as it will make things harder to do) if this is what your wondering, it is easy to do when your used to it, and can do it quite frequently.
(never try an O.B.E. and/or lucid dreams when you first go to sleep, this makes it extremely hard to do! set a clock to 4:30 and wake up then, then go here or a different forum or another lucid dream site fro 20-30min, then go and try it!
works alot better
