I sort of believe the seeing-in-the-dark thing. I was at an LSD party with my friends one night and we took a black frisbee out onto an unlit field (no moon) and threw it around without once dropping it. We just knew where everybody else was and where the disc was at all times. I dunno, maybe we could smell the frisbee.

Contrast in the dark is far better on psychedelics, I assume because of the massive pupil dilation

Maybe the elevated brain energy along with the will to survive or to avoid imminent death might coerce other areas of the brain to align with survival.
