I have lucid dreams a couple times a month. I never try to have them it just happens. I usually am somewhere then realize its a dream and just do random things...mostly jumping really high, flying, and banging hot women until my dick blows up.

I've read if you spin around while lucid dreaming and think of somewhere you want to go and something you want to do it will happen. I always forget to do that though because I get excited.

During the day you are supposed to look at a digital watch like every hour and after awhile you'll just start automatically doing it, then you'll do it in your dreams and when you look at digital clocks in dreams they are all fucked up so you'll know you are in a dream...something like that.
