Before this morning I had never had a lucid dream, I had tried for ages and I just couldn’t do it. Then I found a method online that worked on my first try.
Set your alarm clock to go off about an hour earlier than you want to get up. Wait a few minutes after you wake up (try not to move too much), and then drift off back to sleep while thinking of a tree or a ladder, once you see it in front of you, grab it and pull yourself up and you’ll fly!
A way to wake up is to (while you’re dreaming) close your eyes, then open them again forcefully and hopefully you’ll wake up. You may or may not be able to move once you’re awake, but wait until you can move your head and then you’ll be able to move all over again.
