From Quora:
I keep smelling a weird smell. Nobody else smells it. It’s been going on for a year. It randomly gets really strong. I had an MRI and the results came back normal. Does anyone know what this is? My mom and dad kept smelling this horrible horrible smell in their bedroom and bathroom and sometimes closets. My mom smelled it one day and she just had had enough at that point. She stomped her foot and yelled, “I don’t know who you are or what you’re doing, but you’ve GOT to do something about that smell!!” She left the room for a little while and when she came back…. some of my dad’s cologne had been sprayed. She was the “only” one home.
