This is a lot like spirit diving, without the risk. So, here's the story: When I was about seven, I noticed that I could actually gain partial control over dreams. I could control my dream-body and the dream itself around me. Only now do I notice the importance of this. If you have had repeated lucid dreams (dreams that you can control yourself in) you probably already have this dormant skill. This can be used for travel into others' dreams, or into the mind-realms I mentioned earlier. These realms are parts of the 'sleeping' consciousness that connects us all, a universal force second only to heaven itself. The realms may range anywhere from completely empty to cluttered with beings. Remember, the entrance is through your subconsciousness! I am not responsible for any injuries.
