[Doc Faustus]

You can't entirely dismiss it as schizoid phenomena. Does it happen wherever you are regardless of history of a place? If you were staying at a Holiday Inn would it happen? If you slept in your car would it happen? If so, then you might want to consult a neurologist. Might be safe to consult one anyway as hauntings aren't always accompanied by random foul stenches, in fact seldom are they. The perfume is concurrent with some hauntings, but the stench seems off. It accompanies hardcore hauntings, but that's serious stuff. Unless you live in a place where a cult committed mass suicide for Satan or a place with a mass prostitute grave under the basement, foul miasma of death tends not to happen with hauntings. I lived at a house where slaves were lynched outside that was also the site of a trolley crash but stenches never accompanied the fouler of the entities there. I'm a firm believer in ghosts, but I would still say talk to a doctor about the sensory input. A surprising number of medical professionals are actually openminded about hauntings and won't say brain tumor unless it looks like a brain tumor.
