I've tried my hardest to train myself to become lucid but its damn fucking difficult to do.

I've done it a couple of times. The best one being where I was on a road, became lucid and thought what could I do. I decided to throw an airliner in to the sky which was driving past. Then had various shoppers in Debenhams suck my cock.

Your best bet is to wake up a few hours before normal, do something for an hour or so and then go back to sleep. Thats when it usually happens to me.

Also watch Waking Life. It has alot about lucid dreaming in it as well as being a fucking great philosophical film.
