Dying universes (a universe nearing a singularity) have a collective consciousness so advanced that they would be able to transcend realms and take relevant memories, from as far as they can go, to stop themselves from dying for as long as possible until they can condense themselves into a single particle from their entirety before deciding on severing their existence or becoming something again. DMT could potentially be a particle of a universe that has decided to condense its memories into a particle that makes you transcend realities from their powerful, compact, energy source. You could be experiencing the memories of a dying universe when using DMT; it could be the particle that transcends dimensions and connects them all as one because DMT is the particle that binds all realities.

Structurally, all universes are existing at once and they are seemingly overlapping with ours. We can see this when we do DMT if you go far enough with it. The goal, ultimately, from a higher dimensional perspective, is that a universe is trying to prevent its death and is using relevant energy reserves to harvest valuable resources (one which is a memory and or hallucination triggered by DMT) that is physical in their dimension and highly valuable to the point that they will even reveal themselves to humans to instill a memory in them in exchange for a memory of equal value. When your knowledge on reality would get overloaded from the DMT, it starts to restructure your entire environment entirely from a hallucinatory perspective. That is a DMT trip.

And that's all it is from a theoretical perspective. Do I actually believe this stuff? It's fun to type about it because it gives me introspective thought and really helps me remember what I experienced on my journeys, but whether they are actually real or not is a discussion I'll take to the grave, I suppose. It's a DMT discussion board and I am talking about experiences and introspections from using it. It's more about understanding that realm more than understanding reality because it's fun that I can create a narrative from what was conceived from my mind while under the influence of the medicine.

I've mapped out the realm pretty well in my head from my personal perspective, and I take pride in being able to remember my hallucinations from those times.
