I dream too, very often, most every night. My dreams are very "real feeling" where I can physical wake up with the pains, tears or other sensations that relate to the dream. I too seem to have most control over them but there are always a few that I dont. My nightmare are more so a depressed, scary fearfull type dream. I usually have a hard time determining dreams from memory more so then a dream and reality, If that makes any sense.
