its when you are aware that you're dreaming, still unconciousish, and can control what you do in the dream
Almost, but not quite right.
A lucid dream is defined by the fact that you are dreaming, yet know it.
It's only posible by being conscious. (Technically, sleep is different from unconsciousness.)
im kinda confused about lucid dreams. is it when something in reality affects your dream (like a noise or light) or when you are consciuos yet still dreaming? because i am sometimes conscious and still dreaming, but i just assume thats because i really dont want the dream to end, so i keep thinking it out in my head.
The second one is exactly right, but the first one CAN help you start one.
They've (The lucid dreming community) have made, used, and proved the CD's work in helping start them.
They've also made special devices that are sorta like that old virtual boy gaming system mask thing, or quite simply; they look like night vision goggles that flash lights at different intervals to stimulate your body into becoming conscious.
But you don't need that stuff, some people are naturals at being able to have them at will, though most people have at least one or two during thier lifetime.
If you want more info, just E-mail me or send me a PM or something.
Most of the stuff you can get from that Wiki page, but I don't mind helping.
It's one of the two things I wish everybody could experience at least once: Parkour and Lucid dreaming.
I guess the thing is that everybody does, but don't know it.
Awareness is nice. Freedom is nice. I have both, do you?

Wow, I'm siggin' that.
