It seems to me that this phenomenon of "representational drift" fits well with the results that show that every time a memory is remembered, it is essentially deleted, and re-recorded. Given what we know about how memory and experience make use of large swaths of the same neural pathways, it would make sense that this is the case with re-experiencing sensations too, not just re-remembering them. And if that is the case, then it would make sense that it's possible for these representations to be re-recorded in a different place or in a different way. For example mixed together with other neural wiring that is correlated but wasn't there when the original representation was made (basically de-duplicating the file system). It would also suggest that either pathways are mutating, or different neural pathways are "competing" for the right to be the ones to process a given input (and if it's the latter, then it also implies that there must be some kind of fitness function "how well did this pathway process this input" that allows a new pathway to win out over a previous one).
