I've been thinking that the best thing to do for induction of a lucid dream while I am asleep, would be to have something vibrate a couple of times under my pillow. This would penetrate my dream but not wake me up.

A cellphone would be good for this, since it could be set in advance, and it could be set to go off during waking life as well, as a signal to do a reality check. This would create continuity between waking and dreaming life. It could go off every two hours or so, day or night.

The annoying thing is that my phone alarm doesn't stop vibrating unless you actually open the phone and turn it off. So I would have to wake up to make it stop vibrating. Are there any ideas out there, maybe for simpler devices? Or could I modify an old phone somehow? I'm open to ideas.
