Don't they? Early on in ARR when you first visit the Waking Sands, I remember at least one of the minor NPCs there complaining about having muddled or conflicting memories (Una Tayuun, I think?).

Though we don't really know what a rejoining would feel like, or if it would feel like anything at all. Maybe a regular person with average sensitivity to aether wouldn't even notice, but someone with high sensitivity would? Or the extra aether wouldn't even register for Eorzeans, given that we were told in the opening of ARR that there's so much ambient aether there that it sometimes makes foreigners ill when they first arrive (though I don't recall that ever coming up again, several rounds of foreigners arriving in Eorzea later...)? Maybe you just wake up one morning feeling better than normal, and just chalk it up to 'waking up on the right side of the bed'.
