Are they really, though? Was he actually remembering them exactly? Did anyone check? Or was he just experiencing the feeling of remembering them? I can sometimes experience the feeling of "remembering" completely fake things in dreams which feel very real in the moment, even after waking up. I have to sit back and think about them for a bit and sort through whether they were actual memories or just plot points within the dream. I wonder if a similar mechanism could be in play once the brain starts breaking down.
