Questions about dimensions

I ran into something the other day that I had never seen before. Someone was discussing 15 dimensions. I thought there were 12 dimensions.

Seems to me that years ago we talked about 7 dimensions, and the 7th dimension was 'heaven'...seventh heaven, etc. Then later I learned that we actually have 12 dimensions, and seventh dimension is the dividng line between material and immaterial bodies.

Now, maybe I'm just confused here, but have new dimesions been scientifcally discovered?
Is humanity now becoming of conscious of even more dimensions? I think JD Stone said there were something like 352 dimensions. Are they being revealed to us a few at a time?

The seven dimension theory worked for me for years...made perfect sense If we are in third dimension and are as highly evolved as we are, we shouldn't be too far from Source.

Over the years my awareness expanded, and I became more and more aware of the hugeness of it all. So when someone said there were 12 dimensions, that made perfect sense to me. Right throughout the whole Creation story the number 12 is repeated again and again. Somehow it didn't make me feel farther away from Source though. It made me feel more in contact on a personal level.

Now someone is saying 15 dimensions, and, again, it's making sense to me. Since learning the 12 dimension theory, I have become aware of the Great Central Sun, and the whole sun step-down system. That has to be somewhere between here and Source, so having a few extra dimensions makes sense.

Are more coming? How many dimensions do you guys see? Anyone done any research on this question? I'd love to hear about it.
