a) Muscle memory aka procedural memory is based upon matter adapting to momentum...anything shown on screen represents a captured moment (picture) artificially moved (movie).

b) A question mark (?) implies ones want of answer aka ones ignorance of perceivable origin for suggested outcome...that's not how muscle memory works.

c) Anything on screen represents the flickering shapes on the wall of Plato's allegory of the cave...the real source of light is hidden from the viewer who watches shapes.
