I do not think it has a certain name. Sleep, dream, trance, meditation, and vision are all strange ground with tons of variation. Some times you can enter a vivid dream and still be aware of your body. I eventually learned to cultivate this enough to be able to reach over and shut off my alarm with out 100% interupting an LD. I do not know how often this happens to others, but some times when I WILD I never fully loose track of my body, yet enter a wonderful LD.
