I tend to have DEILD moments because I move, or shift my position in the night, particularly when my long hair gets uncomfortable around my neck or stuck under my arm. It's the movement of turning over that allows me to DEILD because I'm extremely sleepy after three or four hours of sleep (at least) but I've had enough rest that I can start having longer dreams.

I didn't have to practice not moving because I had already done so, and the dream often remained intact for reentry.

I have always been this type of sleeper so it wasn't as much the intention to DEILD as just taking advantage of my natural sleep habits. Lucid dreaming works best when you use the natural style of your sleep habits and work the technique around the manner in which you sleep and dream. You can achieve better WILDs and DEILDs by understanding how you sleep and what your body does while asleep.
