A lot of people mentioned this! The "dreamlike" comparison is common as well. In both cases, you have a network of neurons rendering an image approximating the real world :) so it sort of makes sense.

Regarding the specific boiling-textures effect: there's a tradeoff in recurrent world models between jittering (constantly regenerating fine details to avoid accumulating error) and drifting (propagating fine details as-is, even when that leads to accumulating error and a simplified/oversaturated/implausible result). The forest trail world is tuned way towards jittering (you can pause with `p` and step frame-by-frame with `.` to see this). So if the effect resembles LSD, it's possible that LSD applies some similar random jitter/perturbation to the neurons within your visual cortex.
