I had something going on for a while in my house right after I bought it. Doors would be open, drawers pulled all the way out, lights on and off at night. A couple of times I felt a slight draft and then would smell flowers or perfume and there was one place at the top of the stairs that would smell that way occasionally. Never saw anything but I sensed it was a young woman. It stopped happening after a while but now that I live there alone I wish it would come back, I could use the company.
