I used to have lucid dreams, where I knew I was sleeping and was able to control what happened. That happened a lot when I was very young. Not so much anymore, but strangely if I have a dream where I can fly, my dreams do become lucid to an extent.

I've had the leg cramps too, mostly in my calves but once or twice in my thigh. It is really weird to wake up to insane amounts of shooting pain, endure that for a couple minutes and fall back asleep, only to wake up wondering why your muscle hurts. Stupid body.
