When I wake up after dream, I can't even remember if I've seen the dream in first or third person, lol. It feels like it was in 3rd, but I don't remember seeing my back.
Dreams may be caused by anything, they can be even "hollow"(without meaning or causation)
I have seen it all: from walking ruined cities to the talking with (evil?) mighty entities who would explain how its haveing fun.
Very rarely I see future or influences from others.
I think I had Covid19 at the beginning of 2020, since it lasted for months before I felt normal again. The vivid dreams started after I began to feel better.
Probably just a coincidence.
