Also, I have to say it takes a while to get used to lucid dreams. At first they are so exciting that you will probably only be lucid for a few minutes.

Another thing, when you do become lucid many times you will forget what you wanted to do, and instead fly or do something you would not do while awake. I know from my expierence, the last thing i want to do in a luicd dream is to manual activate a book.
