Controlling dreams

Is normal to contorl dream ?

I control mine sometimes,,, depends how much I'm enjoying...but I can normally only control them within the sphere of the dream

I dont think anyone can control a dream.

its called lucid dreaming, its kind of like concious sleep almost. There is a part of the brain that gets deactivated during REM sleep. Once this area is activated and the recognition of dreaming occurs, you almost let dreams continue but be conscious enough to recognize them. Most people have this happen when they get up from sleeping and go right back to sleep,
scientists control it by monitoring when a person enters REM sleep and then using some kind of stimulation like light or sound or a vibration on the body to stimulate the pons in the brain to activate a lucid dream
