I've often experienced what I like to call 'déjà-vous at scale'. Many times while re-watching a film or re-reading a book, I recognise that my mind, triggered by some apparently inconsequential detail, has spawned a series of thoughts identical to those I had first time around at that very point in the narrative. This has happened months, sometimes years apart. I'd be interested to know if this effect has been studied and what the conventional term for it is. Occam's razor would posit that I am simply experiencing déjà-vous from a moment ago, but the qualitive feeling is very different from the déjà-vous I am obviously familiar with.
