Welcome brother!
You've come to profound realizations, it is wonderful to observe how one can progress further into the truth.
After all meditation is state of witnessing. Just pure being.
I would be happy to hear more from you about Astral projection, I have tried but whenever I feel my astral body is ready to leave physical body it always pulls me back, i feel there are still some energy blockades that need to be cleared.
Love brother!
