Everything I read on Lucid dreams points to you needing to be asleep for more than 4 hours but last night I was only asleep for 1 hour, when I thought I was awake laying on my bed looking down at the foot of the bed I noticed that my arms could not move no matter how hard I tried, right there I knew I was dreaming so I made a nude women appear but I couldn't get to her b/c my arms wouldn't move....so I tried my feet and they worked so I kicked them in the air and it woke me up but it appeared my eyes were already open bc I was looking at the same part of my bed as in my dream. So I layed back down and it happend again almost instantly.....I had to kick my legs to wake me up again b/c I couldn't move.
