The night before last, I had a dream that was literally screaming to me "I'm a dream! You can go lucid now!" ... but I just couldn't remember to do a RC for some reason.

The funny thing is that I also had some of my typical lucid powers, such as super-speed, super-jump, and teleport (didn't try flying). I just somehow knew I could do those things, but never made the connection to it having to have been a dream.
