Just my $.02
When you go to sleep, you see your "family". When you don't sleep, your "family" comes to remind you.
Are they ghosts? Or like dream people? Or real family members living?
I think with every choice we make we create parallel realities with parallel identities. And these identities can make contact with us.
My guess, spirits can play "had Boupstarnm done ______ this would be his life..."
So I mean kinda sounds like ghosts but not necessarily non-living.
IMO schizophrenia is a combination of negative thought loops combined with spirits.
