If a person have a brain disease, and dmt place comes from our minds, he/she will continue to have that brain disease in his trip BUT if dmt place has nothing to do with our brain AND it is our consiousness that do the trip (assuming brain and consiousness are 2 different things) then his trip will be the same like ours trip. In other words, his mind illness will affect the trip (if dmt place comes from our minds). Let me know if it is clear to you now eg

When i say "real" i mean if the dmt world came from our minds somehow or if it actually exists and just dmt allow as to "tune" our mind to that world.

But i said, it is strange cause it is still different than NDE

For example chech this random NDE i found in youtube, there is nothing to do with a dmt trip
