seems most likely yeah. from the occasional spoopy ghost shit it does seem like there could be something else although i feel like that is a phenomena we haven't been able to study and people just attribute it to "this literally means baby jesus is going to come and guide me to heaven and i will feast on milk and honey, because my drawer opened by itself a couple days after my neighbor died." even if something we'd call a ghost is an actual phenomenon, to my recollection the abrahamic religions do not talk about this or tell you what they mean etc. there are actual quantum entanglement processes going on in neuronal activity (it's called the quantum brain) and i wonder if consciousness attempts to survive beyond the brain as some kind of electromagnetic network, but it seems unpredictable (doesn't happen for everyone, not everyone makes a ghost). even if it can do this however it's not like real afterlife, i'm not sure if the ghost is really even conscious or has its full capabilities still, it's not like you can just talk to a ghost like a normal person and ask it about what happens next etc. tellingly they seem unable to communicate and sometimes seem unaware of their surroundings, and i mean how would a disembodied brain even see or take in new information? it also is not an immortal afterlife. where are the ghosts of the cavemen, the romans etc? seems to dissipate after a couple hundred years max. and otherwise yeah it's just nothing.
