I have been working on my dream recall for over a week now and it's going pretty well. So far I have only had one lucid dream that didn't last long. And I came across this, (Search "Beautiful Memories Lucid Dream Induction" on youtube. It runs 90 min. I can't post links yet)

It is an audio file that helps induce lucid dreams. But do i play it when I go to sleep, or do I like wake up after 6 hours of sleeping and then play it?
