So I'm jealous. Maybe that gives you a clue.....you are on your way, a door has opened, and it seems the next step is to overcome fear, and start asking questions during the experience. Move into it instead of being freaked out by it. Sounds like phasing, you won't have to "project" as you're already there. "Projection" is just, IMHO of course, a means by which you can recognize that you're phasing into the RTZ.
I'd say that there is a possibility that these are other lives of your I There, (not in the RTZ, but "beyond" it) if you know the term. Have you ever read Bruce Moen's books? Some of his early experiences seem to match what is going on with you. Not everybody starts with projecting into the RTZ, as it is not necessary or desired for everyone.
