Some observations (A) I could answer this with respect to semi-coma experience, wherein - perception still encounters a "sequence" of events or actions relative to self. But space may not be encountered in such events per se, but only as a set of dimensions typical to mental imagery percepts. (B) Secondly in narratives or myth discrete space collapses and reorganizes itself in experiences of moment. (C) Your question is indeed interesting. Neurologically, lesion analysis could help in identifying loci of perception for time and space. (D) Is a space-time continuum a neurologically observed network?
