Lucid dreaming itself woke me up, often in the middle of the night. I had to force myself to forget to ensured I stayed asleep and got a full nights rest, and eventually I stopped remembering dreams altogether.
Lol, reminds me of my first lucid dreaming experience after a long time of sowing the seeds. The moment I recognized I was dreaming ("I" "was" in my living room) I was very excited and thought "Great, it worked! That means I could try out flying!". So I took off - and bumped my head on the ceiling (1). Woke me right up... :-/
