I REACHED out to a lady on Facebook market place for 1000+ dvds and vhs media she needed cleaned out of the basement of her building. When I showed up I texted the lady and she told me to go in the building and down stairs to the basement so I could start packing them up. I walked in and looked around the main floor for a minute and yelled hello just to see if anyone was there. Being that it was an old building I took precautions and checked all over before going down just so I knew I was alone. I walked down the dark stairs to the basement only lit by 2 lights and an exit sign. I pulled out my phone to record what it looked like to show my wife what I was doing. Right before I got record I heard heavy footsteps down the stairs at me. I hit record, then a voice of a woman says something to me and simultaneously I hear footsteps upstairs and down in the basement by me. at this point as seen on the video I'm scared and confused by what's happening all around me. at this point I said nope, and got out. The lady later messaged me about how it was going and she told me she on purpose didn't show up because the building scares her.
