Hi, I used to feel pain when I astral projected too. I had that problem for years. Then last year I saw what was going wrong. There was someone (in the astral realm) next to my body that was poking me. After that I raised my vibration and the evil entity stopped bothering me. A week ago I had my first painless astral projection. It just felt good. First I vibrated, then I suddenly floated above my body. I couldn’t see anything though and I was glad, because I was afraid of seeing something scary.
