So I have noticed in my lucids. That whenever I do something too much that lets my mind know that I know I am dreaming then I wake up. Examples: One night I was having a lucid and I looked in the mirror, and I kept looking back in the mirror to see different faces and that was when I woke up. Last night I was having a different lucid and I looked at a clock, and each time I would look at it again it would be a different time and that is when I woke up. That dream was the longest lucid I have ever had and it felt like if I hadn't of looked at that clock it would have gone on for a while longer.

I'm wondering if anyone has noticed this same thing, and if not maybe someone could do an experiment and post their results on this thread.
