I am pretty skeptical about the paranormal...but have have enough otherwise inexplicable experiences not to entirely close off the possibility....
A house that I once lived in had built for, occupied by, and was the deathspot of the coroner of the city where I lived.
The grounds had been beautiful at one time, and besides the house, there were outbuildings, like a carriage house, garage, chicken coop, and his home darkroom/laboratory...with old files still there...also, there was a room in the house where I always felt like I was suffocating, and couldn't be there for more than a few seconds without panic. Roommates and I watched as things moved from spot to spot, or levels of things like mayo would rise and fall from day to day, weird footsteps in an empty hallway...
I can't explain, but I wasn't hallucinating, and I wasn't the only one who saw these things, so...?
