I like the idea of mapping Hyperspace, and as a conceptual idea, the multidimensional fractal with a black hole center is as good as any. I have been drawn to Rob Bryanton's 10 dimensional explanation, and we have talked about it in other threads. I will put a youtube video explaining it below.
I find that actually mapping a place, though, requires sending people to the places and surveying it methodically. Conceptual maps of mythic lands give way to topographical maps with accurate placements of rivers and mountains and lakes etc.
SWIM finds that with DMT, there are distinct rooms (or networks of morphing rooms with similar aesthetics), and spaces that share some fundamental aspects... not the least of which being the nature and look of the entities one encounters there.
The blue vs. gold spaces described in a post above are also very familiar to SWIM. They may have something to do with the amount of light reaching SWIM's closed eyes as suggested here. This may be why the tilting of the head makes a difference. SWIM also notices that pure white spice can lead to a bluer and more clinical space with more sci-fi like entities... more yellow and jungle spice tends to add oranges and purples to the mix and leads to a more emotionally welcoming space with more friendly entities.
I would guess that the combination of spice type with light creates the end result. Also, squinting or squeezing one's eyes tighter can change the focus and the dimension perceived. SWIM is able to be in one place, squeeze his eyes and go somewhere else with other entities there, release his eyes and return to the original space. In fact, different levels of squint can result in different interim spaces. With some control, he can actually tune into 8 or 9 distinct channels in this way. This could be an important tool for others trying to navigate.
Here is the video I mentioned:
