I've only had two lucid experiences, and they were very short (too short for me to do anything besides freak out!). I loved the brief feeling, however, and want to feel it again. I've started doing dream recall, but I've got a few questions.

First, I can only remember my dreams on the weekend, when I don't wake up to my alarm. How can I wake up without using an alarm?

Secondly, do these pills or machines actually work or are they just scams?
