Of course. Yes to both, stars and where God resides. So now we have three heavens. The one where God seems to reside which you curiously called heavens. The one where the celestial bodies are (stars) and where the birds fly.
The firmament is not the sky. It divided the waters from above from the waters below and is where the celestial bodies exist. The open firmament of heaven is the sky where the birds fly.
Wait and see is all I can suggest. Whether it's a sanctioned mystical experience or Not, what else can we go by but what we know or induce? All around us we see sides to be chosen. Good and evil.
Do you know a way around that?
My only explanation is that faith opens the door to understanding of the world that was and the world which will come when God's world coincides with our world again.
