Rarely I fall into a dream like state but at the same time can percieve whats going on around me in the physical world. The first time I was sitting in the back of a car (dream) and at the same time was able to view my physical surroundings. I was lying on the couch at the time. It only lasts about 30 seconds (to my knowledge) and I was completely unable to move (physically). The 3 times its occures it has scared the shit out of me and I dont have a clue what it is. All three times occurred the night after I had X. Is this some form of lucid dreaming or something completely different?
