Yeah it's not something I would call 'easy'...at least it wasn't in my case. What you described almost sounds like a soul braid to me - the braiding or 'merging' of two souls. I've come across a few people who had that experience.

I don't get involved with any astral stuff - as I'm doing my best to focus on the physical to help myself get grounded - focus on the physical but in a 'spiritual' way.
