I keep talking about this.
the language I am using is a mix of of gestalt psychology, and neurology.
the principle noted in neurology is neuron signal fading.

after peak signal transmission, decreasing neuronal pulses continue for several milliseconds fading to nothing in about 1/6th of a second.

your whole gestalt of experience is constantly being built up by these fading signals from all sensory detectors.

on entheogens, these signals fade more slowly, sometimes lasting to more than a second, depending on dosage and type of entheogen.

accordingly, before one gestalt has faded another becomes fully active, and, to be precise, if the fading has been extended to 1/3 of a second you have two gestalts, pushed further you can have up to about 30 coincident gestalts or apparent dimensions - all apparently equally real. (after this signal density it becomes next to impossible to perceive anything - some call it ego loss, recognition and associative thought as we know it is drummed out by the chaos of input that has not faded)

multiple limbs, or limbs that extend through more than one gestalt frame or 3-d limited space are very very common.

visually when you perceive a multiple (say 4 copies of one view by extending fading to 1/2 to 2/3 of a second - ~level 3-4 of salvia...) if the stacking of gestalts persists, in the next gestalt you can double it to 8 copies, and by the time you get to 32 layers, millions of copies of living moments will seem to be equally real or unreal.
