Only correlation i found between "ghosts" or "delusional something" was fungi.
Consider - the neutral scent olfactory system, whatever it's totally for, is tied into your memory and emotions directly, with pretty much no
filtering.
What if an evolutionarily useful thing would be to encode a 'last message' sort of pheromone, with a purpose of warning away other animals in the pack
from a non-obvious danger, or one that basically states 'I got eaten by a saber tooth that lives nearby watch out'. If one of the last acts of a
mammal were to put out a unique signature that let the others know about particularly dangerous situations, it would benefit the group's survival.
You've already GOT pheromone emitting glands, and you've already GOT a sensor system that would be easy to adapt for this, so it's not a big step in
terms of evolution to add this. So, when a critter is facing the last gasp, or thinks it is, it might emit a persistent chemical signature that serves
as a warning for some time to come.
Cut to - ghosts. What are some of the salient features? Not everyone perceives them. They're associated with 'gut level' emotional reactions like
fear, dread, hairs going up on your neck etc. They're associated with 'last gasp' events in the ghost's last moments as a person, or with extreme
situations where the person would have expected to die. You mostly perceive them inside a closed structure that is protected from the elements where a
chemical cue might be expected to persist. You can be rid of them by applying a masking agent (fuming, priests with incense). You don't often perceive
them outdoors except in locations where many people died or are dead (battlefields, cemeteries), and at those places enough 'last gasp' pheromone
might be expected to last through some weathering. I put it to you that the entire 'ghost' phenomenon might be no more than a vestigial mammalian
warning system based on pheromonal cues.
