Most of you will have heard that you must believe you are going to have a lucid dream to have one. Well, this is true.
Recently, if I've really wanted to have a lucid dream I often can't. But if I say out loud during the day "I think I'll have a lucid dream." I get one! This belief that I have the freedom to choose really helps boost my lucidity. And heck, I guess I do have the freedom to choose. Because it works!
Just in case you've ignored this way of getting lucid, be sure to not discount it just because it seems like a newbie tip. Its no joke.

Don't just believe. Know you are going to have a lucid dream. Because you are.
