What are some of the best sites for discussing Astral Projection or other parapsychology?

The threads on /x/ get fuck all replies and I don't want to have to use reddit

Can a Christian practice hemisync or does it count as an occult practice? I've seen angels, aliens, demons during hemisync and would like to try it again but I fear sinning. ChatGPT said it is sinning if you're trying to contact spirits with it but I was curious what /x/ thinks? Aliens in particular I think are neutral and interesting to contact. I had a dream about a grey alien smiling at my bedside after a hemisync session.
