I think it's important to stress the fact that DMT does not feel like being thrown in a meat-grinder, or being impaled in a car accident, or any other grisly way to die. Really, it might be more correct to say "Death might feel like a DMT trip" because many have experienced a DMT trip, but it's not every day you get to experience death. Of course, it makes for a less interesting title.
People experience death (and psychoactives) in a variety of ways, and its metaphorical usage reflects that. The meat-grinder sense maps better to stimulants (ie., caffeine, amphetamine, etc) whereas the exhausting, perhaps harrowing and enlightening sense of death is what we tend to experience with the psychedelics.
Before I reached this state I was seeing math formulas everywhere. Basically when my internal thoughts stopped, that is I was experiencing reality in the rawest form, the only truth we have in the universe is math, in all shapes and forms, we live inside the 'body of god' that is math, but of course, so extremely complex to express in our 3rd dimensional world.
