I'd like to say that I have been projecting since 2008 and I can say with absolute certainty that demons do not exist but in your mind. I never experience them because I simply don't believe in them.

OOBEs are absolutely harmless. All you need to know is that there are no monsters out there to get you.

Also, Robert Bruce is a charlatan. He is feeding people's fears about so-called astral projection in order to make money. Self-defence...pft. The only self-defence you need is knowing that nothing can harm you. The people who read his books start to form a biased belief-system in their minds which will then manifest when they project. Bruce is blinding you. The best way to approach OOBEs is with a fresh perspective.

There's a lot of tosh being published out there!
