(This is possibly controversial, so if the thread's closed I understand.) I was reading a Reddit thread about coma patients' dreams, and some of them seemed possibly PL related. (One person thought they were old, another thought they were French.) I've also wondered about hallucinations, or even occurrences as simple as fever dreams. However, given that these are dreams people have while they're clearly not "right", how much should they be taken into account? Are they actually having PL memories, or is it just the brain confusing memories and stimuli?
