Byron doesn't astral project, he might understand it theoretically but until you've separated your consciousness from your body and left both extremely vulnerable, it's hard to grasp.

I project onto the spirit plane, the afterlife. The longer you keep the two parts of yourself separate the greater the chance of getting trapped there if your physical body dies, or putting yourself into a coma like state where they remain separated. In my case, it also means if I'm not careful my body is open for possession.

12 hours is a long time without proper training.
