I love WBTB. I (sorta) had a lucid dream the first time I tried it out. But there is one major problem which I am sure many people have. I live in a house with my family. This means that I can't have an alarm that is loud. The alarm doesn't wake me up if its on vibrate. I was wondering if there are other alarms that are quietly effective or if there are any natural ways to wake yourself up at the right time.
