My parents house has been haunted since it was built. Family, friends and neighbors have witnessed weird things and I have and I believe in spooks to an extent.
My wife worked in a hospital built in the 1950’s which has had remodeling and movement of departments over the decades. She was in administration and finance and that suite which was locked down at 5:00pm was the old ER area 40 years ago. Many nights during month end she would be working late and here people walking around in the office suite outside her office which was at the far end and last office of the suite and doors opening and closing. She would get up and check to find all as should be. Then she would start hearing voices out in the secretary area and walk out and look, it was a straight shot view from her office door to that area, nothing there.
Finally she decided to close her door and crank her radio when she had to work late and drowned out the noise. When finished she had everything shut down and her purse on her arm and she would say aloud time to go and hit the lights and zip down the office suites to the main door and out quickly. She never believed in ghost until she stayed in my parents house and worked at that hospital.
After you have a few experiences you just can’t doubt it anymore. More are not exposed because they are indeed rare, but when you find the right location they can be quite common. I had a friend who bought a real and true haunted house. I used to house sit while he and his wife went out of town every week end.
I had three experiences there by myself three week ends in a row. I am a spiritual person so I tried to just understand that I was in “their space” and respect it. But the third experience was way far evil and physical. I was done house sitting that house.
I worked on the basement floor of a hospital. The morgue was across the hall. I never saw anything, but all of my overnight staff had seen or heard things. They would just call out for “Martha” to knock it off, they had to work. And it would stop.
I was their supervisor for about two years before I heard about Martha. I asked each group that worked overnights and they all “knew” Martha.
