Dendara Light Bulb as Expanding Torus and New Reality Portal

The Dendara light bulb, (it's popular name), and is sometimes equated to a plasma tube. I've done that, but kept learning. Would anyone care for an alternate idea?

Near letter A and B is that flower-with-cones symbol that shows an outward flow direction, and the snake also shows that flow direction, even on image H without the surrounding "bulb".

Near letter C, D and E are examples where the brim of a cup is the origin. The brim in symbolism represents the barrier (and portal) to a new reality. Image F shows equivalency of the cup brim to the flower-with-cones.

Image G is somewhat like F, and the semi-circle above the brim is the new reality. (The animals are side flow symbols).

Images M and N introduce the idea of "bubbles", which have been an analogy for the outer barrier of a torus or a reality, for a long long time. Remote viewers see bubble symbolism a lot.

Image I's tail is doing an outflow upward, expanding into the inside of a circle torus symbol. The star-symbols mean energy, not in space.

Image J is a different example of a snake expanding and becoming fiery. Image K and L are modern, but the artists clearly know symbolism, showing the expanding diverging flow above the portal. I also like image K because inside the torus there are strata layers.

Unfortunately for us, the Dendara snake isn't multi-head, but imagine that it is, for now. Here comes the idea:

What if the Dendara bulb is the "inflation" of a new torus and/or a new reality beyond a portal, and it has a bubble as the outer barrier.
