I've had a lot of issues with falling asleep in a WBTB.

First of all I should explain how I've been trying to lucid dream. I wake up from my alarm clock during a REM cycle and get up for a few minutes. Then I try to day dream a scene and passively let my subconscious mind add things to it until I fall asleep.

Unfortunatley, I only wake up later to realize that I had a dream in the scene I created, but I had lost consciousness. I figured that this was happening because I was not awake enough, but if i stay up longer then I cannot fall asleep for several hours.

Any advice would be appreciated.
