Thread: Please Someone Help!

First of I would like to say that I havent had a lucid dream in a while. But i noticed that in most of my dreams, when i want something to happen it usually does but I dont know its a dream so i guess you can say I can control dreams really well but I just dont know I am dreaming. Does anyone know why.
And I also wanted to know if I used my computer and set it to go off after 5-6 hours with it playing " you are dreaming" or "do a reality check" repeatdly with headphones. would this induce a lucid dream. Thank you!
