Now, this only worked once, but then again, I've only tried it once. I'd like someone else to try it, tell me their results. Personally, I had a very long, vivid, LD after doing this.

Put them on an mp3 player. Stay up until you are tired. (Make sure you have time to sleep in in the morning). This is not mandatory, but it is recommended.
Before you go to sleep, drink some apple juice, eat a banana, some salty foods like beef jerky or pretzels, and any aiding supplements you normally take. Use headphones, and lay in bed. Listen to the recall aid mp3 first, and stay awake during it. Let it play into the next one, (Lucid 3.0) which is about one hour long. Put it on "Repeat" so it doesn't start playing any other songs. You may fall asleep during it. But, DO NOT try to fall asleep. If you are tired enough, your eyes will close on their own. If not, DO NOT force your eyelids shut. This will only make you stay awake and conscious longer. While you are listening to the second mp3, think about the following. Whisper it or mouth it about 10 times, then just constantly think about it.
1. I will dream tonight.
2. My dreamscape will be a blank area, with no objects or walls.
3. There will be a white board in front of me, which says "Reality Check"
4. Two small men will appear, and dance around, singing "Reality Check, Reality Check", and will start performing reality checks.
5. I will do as they do.
6. I will become lucid.
This worked for me, I had the longest/most vivid lucid of my time.. somebody try this and tell me if it works for you.
