A True Story

I swear! 
Around 1991, my soon to be husband and myself decided to rent a home together with our children while we began to shop for a house to purchase.
Depending on visitation schedules, we normally had between one and five kids living with us at a time, so we needed a fairly large home.
Luckily, we found a rental in the city of Fremont, California, which suited our needs.
This was an older building, built around the 1950s, but not what I consider an old house.
The weekend before moving day, the children were all with their other parents, so we had the opportunity to begin bringing a few items over.
While putting some things away in the master bedroom, we suddenly heard heavy footsteps on the roof, right above our heads. We weren't expecting any work to be done, so husband-to-be headed out the back while I went out the front to see who was up there. No-one was on the roof, and there were no ladders or work trucks nearby!
We went back to work, talking about this potential ghost,when it happened again. Once again we head for outside, in a much bigger hurry... and still nothing and no-one was on the roof.
For a while, these footsteps seemed to be contained to above the master bedroom, and over my eldest daughter's room. If there's one person a spirit should not haunt it's this girl, because she won't put up with it! She actually seemed more irritated than scared by the whole thing.
Like most families, we liked to gather together in the living room to watch TV in the evenings, and you guessed it- the ghost began walking above there!
Now I've heard the odd noises houses can make, creaks, groans and whatnot- but this sounded exactly like a large man in workboots going about his business. The strides could actually be followed by us witnesses below.
Finally one evening we heard the footsteps, then there was an ominous quiet. My soon to be husband says "Hon..."
I heard two of the kids audibly gasp, and turned my head to the left just in time to see the microwave levitated about a foot above it's stand! It moved about four feet away, and dropped to the floor with a crash.
The microwave had been placed partly blocking the view out the kitchen window, something I had to do due to size constraints.
Not wanting to further scare the children, I commented that the ghost must not have liked the view blocked, and I picked the appliance off the floor and put it on the kitchen counter.
After that we'd still hear the footsteps on the roof, but as far as I know the spirit never came back inside. Shortly thereafter we purchased a home and moved.
My husband was a telephone installer/repairman, still working in the area when he was called to install a phone in that house. It had been turned into a sort of half-way house, with about five men residing there.
The customer remarked to my husband that he definitely wasn't planning to stay there long... and my husband didn't have to ask why.
