I found this file at Warp My Mind, listened to it last night, and had a lucid dream! I’m not saying this was the cause, but it definitely didn’t hurt my chances.
I uploaded it to my Dropbox so you don’t have to sign up for Warp My Mind and wade through all the crazy things on there. Here’s the link: https://dl.dropbox.com/u/10664407/Cardigan%20-%20Lucid%20Dreams.mp3.
Be sure to reply if this has any effect on you!
