About half of the dreams I had as a child were lucid dreams. I used to really look forward to going to sleep, because the dreaming was so damned fun.
I still have lucid dreams on occasion now... I think I usually can if I want to, but it just kinda lost the appeal a few years ago. I guess after years and years of controlling your dreams, it gets just a little boring... it's more fun to let my mind run wild and let the dream control me now. Sometimes, when I think about it in my dream, I'll take control just for a few moments to see if it still works. It always does. My theory is that if I'm able to "think" about it, then it's already pretty much a lucid dream, and it's just up to me as to whether I want to be in the driver's or passenger's seat at that point. I suppose I probably have plenty of dreams where it never occurs to me to take control, so it's hard to say if I could turn those into lucid dreams or not.
It's a little odd, but my lucid dreams were/are never
completely lucid. They seem to have to stick to a general theme. In other words, much to my dissapointment, I can't halt a nightmare in the middle and conjure up Kathy Ireland to bang a few times. I can, however, stop the "nightmare" and wander around whatever environment I happen to be in, interacting with it on a somewhat concious level. Unnatural things like flying are fair game if I think about them, but that seems to happen less and less often now. It's almost as if the lucid dream activates a
portion of the brain that isn't typically active during dreaming, but not the whole thing, so you don't quite have
full cognitive abilities. For example, doing math while dreaming tends to be exceedingly difficult to me (it's one thing I usually try to do if I think about it, and more often than not it ends up waking me up).
The most bizarre dreams I've had were when the dream seemed to have run its course, either at my control or not, but the dream didn't end (at which point I was definitely in control)... kinda like a movie that's over but there's still just a lot of empty scenery on the screen and you can't leave the theater. It's realy frustrating, and boring. They seem to go on for hours and hours... just wandering around. Thankfully, they seem to happen much less often now. When I was younger, about the only thing that had any effect was going to sleep in the dream. Sometimes that let me "wake up" from the dream. Weird.
I think I'm kinda rare. Very few people people I've talked to about this have ever had a single lucid dream, much less with the consistency I once did, and still do to a lesser degree. I can remember the first lucid dream I had as a child, and I was fascinated by it. I think it was probably sheer "luck" that I had the first, and the fascination that allowed me to sort of develop that "skill" if it is even considered one. Strangely enough, I never bothered to do much reading about it - I suppose because everything I wanted to know about it I could learn by experiment.
People often think I'm nuts when I tell them about the cool stuff I dream about. I have really fantastic dreams... mostly science fiction and horror now, but they're almost always fun. I tend to remember most of them to some degree or another each morning, but they quickly fade. Were I ever to have the time to write a novel, I think I would have no problem coming up with absoutely insane plots.
One think I'm certain of... you remember dreams more vividly when someone wakes you up in the middle of one. If you don't think you dream, have a friend wake you up in the middle of the night a couple of times a week. Eventually, they will do it during a REM cycle, and you'll never wonder if you dream again. Also, I tend to remember a lot more of my dreams that happen in the morning between snooze alarms. From what I understand of sleep cycles, the body shouldn't enter REM sleep until it has been asleep for awhile, but I seem to drift in and out of dreams when the alarm is going off every fifteen minutes or so. Maybe I never fully wake up when turning off the alarm. That could possibly explain why I'm late to work just about every damn morning, and why I've gone through a dozen alarm clocks in the past decade.
