A while back I had a dream. This dream was about me lying in bed and thinking to myself about a certain mythoogical creature. It seemed like as if I was actively retorting and freely thinking about this one subject. No, I did not realize I was dreaming, and that sort of heightened "alertness" only lasted for the amount of time I was on my bed. Shortly thereafter I quickly lost this state.

Has anyone out there experienced this before? Is this a sign I'm getting closer to LDing? Or is this simply a normal thing that can happen in a regular old dream?
