Recently I have moved 1000 miles away from where this is happening, but my coworker and close friend is still having experiences with this.
Not too long ago I lived in Vermont and worked for a property management company. I worked in an area with a lot of tourists and obviously ski mountains. So, I worked as a housekeeper and property manager at the same time. There were about 100 houses that we checked and kept accounts on and several we cleaned.
Several of them may have been haunted, but one in particular is the oddest of them all. In this house, my coworker and I were working downstairs and we thought someone had come in. It sounded like someone in heavy boots was knocking them off so we ran upstairs to see who it was. No one was there, but it sounded like there were boots being kicked off upstairs. We checked the garage and driveway, no one had pulled up, so no one could be upstairs. As this was a new account, we shrugged it off to the house settling and went back downstairs to clean.
A few minutes later we heard what sounded like something heavy being thrown against a wall and boots being knocked off. We ran upstairs to see if anything had happened, and nothing was there. So we set up a recorder (on my phone) and went back downstairs.
We stayed down there while the recorder was on upstairs and it sounded like boots at first, then something being thrown against the wall a few times, then boots. It went quiet so my coworker and I started to go back upstairs. As we reached the steps, the crashing started again, then stopped. I continued upstairs with my coworker following reluctantly behind. Nothing was moved upstairs. I checked the recording and it had picked up the noise on my phone.
The next time my coworker was cleaning there with the new girl and she filmed where she thought the noise was coming from, and the other corner as well. In the corner and the fireplace in the video is a pulsing shadow that stops when the noises start then starts pulsing again when the noises stop. It covers about 10-12 feet from the ceiling to the floor in that corner while the other corner is empty.
I was wondering if anyone has any similar experiences, or might know what is going on with this as my coworker is still working there and is being frightened by it.
