The subjective experience of 5-MeO-DMT can involve a feeling of dying, loss of self, and a state devoid of space, time, color, sound, or physical sensation.

“And you think you're going to die. You said, "S***, this was a mistake. I'm going to die," and you die. I died. And in a sense that myself was gone, Christof was gone. There was no voice, there was nobody. ... But you don't see, you don't hear. You get totally cut off from the world. But when I say "I," it wasn't Christof. It was conscious, there's no question. I mean, whatever remained was man, woman, child, God, angel, demon, but it didn't experience anything except a point of overwhelming brightness. So there wasn't color. There wasn't left or right because there was no space. Space had collapsed into this point. There was no stereo or texture. There was no pain. There was no pleasure. There was no sound, no smell, nothing. There was just this point of icy bright light and terror and ecstasy. That's it. Three things: bright light, terror, and ecstasy. For time, there was no time. There was no perception of time, right? Right? And so, it wasn't too long or too short. It simply was. There was no space, as I said. There was no self. So all of that was gone except terror, ecstasy, and light.”
