I came home from work a couple hours ago from posting this and took an hour long nap. Interestingly, I had a Lucid Dream. In the dream, I consisted of foam ( like on top of Root Bear ) and I was floating in space. I was completely aware of myself and of what was going on around me, I was like this is so cool, where should I travel? Then suddenly I woke up. I was a little bummed that I woke up but It was so cool.
If you want to try and have a Lucid Dream. This works for me... If you have a red light bulb in a lamp by your bed and play this track as you fall asleep you will go lucid: https://youtu.be/XkNwJow3YOM?list=PLta7j9iHz24m8D5qghqLPjvvIxaGkX9mE
