When I was about 14 I had a nightmare about a certain species? of man which were always in my dreams since I was 4, anywho they were chasing me through these ruins, and then the scene changed to an old hospital wing one that looked like it had been part of a sunken ship (greenish, with growth) and I turned around, had my epiphany, said some swears and tore the closer man to me in half, followed by his friend who was now running in fear I easily broke his neck and pulled his head clean off. Anyways I haven't had any control filled dreams recently I have come close, and I have started to forget my dreams, so I was just wondering if you could lose the ability. And if so can you regain it easily or whatever.
