Astral Projection is dangerous.
1.when you OBE, you have to rely on entities and "spirit guides" to help you. You never know what their intentions are, are their power is often underestimated.
2.When you astral project you bring yourself closer to the spirit relm, which means more possible contact with evil entities(Like the entity that forced Erin back to sleep and tried to pull her out of her body) . Can you imagine being a afraid to go to sleep because something may try to pull you out of your body?
So I would recommend against it. I use to want to do it a few days back but for these reasons I don't want to anymore.
