I mean, visual, for example in the sense of covering or replacing your visual field and surroundings (both eyes open and closed) for complex visual geometry, (or visuals so promiment that they are the same with closed and open eyes) and what is the quality/style of it.
I used to to think that this is a trademark effect of DMT, and it can be sometimes achieved with high doses or other pscyh's (I have seen 25i-NBOME usually in that list (and it usually needs lower doses to do so than most of other psych's)).
I have also read that DMT geometry is the most intrincate and "structured/geometrical" out there, but I don't know. Maybe there are other characteristics as how colourful it is or other stylistic variations, in the visuals that differ in DMT and NBOMEs, and soome people find also impressive.
There is also other aspects of visuals that are harder to compare (for example some drifting, distortions or tracers are more likely to be observed/analysed in the NBOMEs, as you have more time to walk and interact with your environment, even though they can be also very strong in DMT).
I know that every psych has its own style so I guess it's hard to compare. Would you say that DMT and 25i are the most visual or you consider other as visual as them (following that reasoning)? Maybe 2C-P or ETH-LAD?
Also this reality bending experience of DMT is hard to analyze. I guess it is partly due to the intense hallucinogeninc headspace of DMT (way more prominent that any NBOMe) and partly a visual characteristic (how the geometry of the space is modified in the DMT breakthrough). What do you think?
