What are the dangers of astral projection?

Regardless of what the other answerer said, she doesn't know what she's talking about. OBEs are not dreaming, nor is it hallucinating. I was never laying down, tired, or sleeping when I'd have mine, nor was I ever on medications or drugs. Sick of people "diagnosing" things they know nothing of. OBEs are very dangerous. There have been people reporting that they've encountered demons, some have been attacked. When I realized it was time to quit, I'd just had my second time getting stuck while trying to get back in. I evidently passed out and came to (don't have any idea how long) with the most excruciating headache, just like I did the first time it happened just before. These were the worst headaches that I've ever had to this date, many, many years later. My best guess would be from lack of oxygen, although I really don't know. It wouldn't surprise me to hear that people die while doing this, although, it couldn't be proven. I just think of the people who die and autopsies and toxology reports show nothing, maybe it was a complication from OBEs, but who knows. But, mine still try to come on by themselves and I must fight to stop them.
