Being new this forum, I am not sure if this has been discussed before. I have had the occasional lucid dream over the past few years (unintentionally). I have been able to achieve lucidity recently quite regularly through sleep interruption but how it happens is kind of strange. Let me explain.

This only happens when I have slept for a while and have reawakened completely (for at least half an hour). When I go back to sleep (after some tossing and turning) I go through this strange experience. As I am drifting off there is a loud rushing sound in my ears and it feels like blood is rushing to my head. I often feel like I am falling but I can't move. I am consciously aware the whole time. The first few times this happened, I was quite scared and fought to wake up. I thought I was having some sort of epileptic attack. After a few times of this happening I kind of figured out that the feeling must be some sort of transition into sleep/dream state. When it happens, I can now go into a dream directly with full lucidity and often with control over the action. I have also had lucid dreams where I realize I am dreaming and become aware but they are much more rare. Have others experienced this and have others become lucid this way?
