Lucid Dreaming?

I had a very interesting time of sleep and dreaming last night in which I had great orgrasmic feelings. The past couple of nights, since returning to my workout regime, I have awoken in the morning with stronger than normal erections. Last night, before getting into bed, I could feel a sense of low level arousal coupled with a sense that I needed to stretch the muscle in my penis. It's hard to explain, but I get that feeling... and I haven't for a long time.... that when my penis is erect I want to try and bend it left or right to stretch it. The feeling I get is exactly like when one has a stiff back or leg muscle etc. and then stretches it until they feel that relief. Not sure why I have this feeling in my penis but I guess it's a muscle too and needs stretching. Needless to say, later that night, in my dreams I could feel great orgasmic feelings and awoke with a very strong erection. Definitely a great feeling!
