Sometimes -- not at all predictably -- "changes" seem to cause my dp/dr to "flare." So, going from one room to another can suddenly evoke the sensation that I'm dreaming, and that the room I just left is hours in the past.
What that may obliquely have to do with "intellect": I can also get a "blip" of that feeling if I'm day-dreaming or planning something, and then abruptly "change" my focus to what I'm actually doing (fixing a meal, or whatever).
