Nope. This is what is called 'cosmology' many times: how you think the world is put together. CAW uses a view that involves 9 different interlocking worlds. Other religions or paths or traditions do different things. (For example, I'm familiar with the concept of 9 worlds from both Norse and CAW sources, but I don't know lots of details about either of them, because this is totally not part of my own tradition/path.)
Now, I *do* believe in the existence and function of astral space (and also of shared astral space): I'd tend to approach the experiences you describe from that point of view. (Which is to say: I believe you're having meaningful experiences: I just think there's more than 9 distinct spaces you can have them in!)
My question with all astral work is: what are your hopes for it? What do you hope to gain/learn/experience/understand that you won't have access to in other ways? For some people, it's a chance to work in a context and space that is not accessible for them in the physical world. In some cases, it's a chance to work with non-physical entities (be they deities, animals, or whatever else.) I've found that once I have an idea of what I'm doing or wanting, it's easier to both do the astral work *and* to make some sense out of the experiences, given a little time.
I was trying to access acacia to find my own inner being and help others who went to the level above acacia. This is what I believe with what I have been taught and read. Hell or whatever being the worst place and the desert above atlantis being the highest. I needed to understand that I am a good person inspite of some things in my life that made me think otherwise.I was counselling myself.
It's partially why I am polytheistic. I don't know what to do now that I have discovered all of this. I guess I could fly around the 9 other worlds, one being Unicorn world that I just remembered but that one has a mirrored world, like an obstacle. It's the malevolent protection spell that was put in my way by a christian counsellor. What can I do, the only thing I can think is that I need to worship on another sabbatt, the last time I worshiped being samhein in 1998.
I think I joined CAW online.
