Ok so I know compared to scary ghosts and spooki scary skeletons, my story isn't as frightening. What really sticks this to memory though is its completely unexplained nature. A few years back I worked in a local supermarket of a chain I won't mention, aside that the uniforms are black. That comes in later. Anyway I was about 16-17, small and generally unexperienced, I just needed extra money while I was in college so I could get the train to see my girlfriend. Call me a modern day romantic I know. Anyway, I hated the work and often took longer breaks than I should, upstairs in the employees room. Now the store is a large square shop floor with a door at the back, leading to a single walkway. At the end of the walkway is a set of stairs leading up to the warehouse room above the shop floor, and the break room adjourning that. No other way down aside the stairs. Ok so I was on break, eating some out-of-date stock, and over the intercom I was called to the tills. I can't remember what day it was, but there were very few of us workers in that night so it seemed busy to us. There was me, an older woman who I think was called Becca, My friend Shaun, and my manager who's name I've honestly forgotten. I responded to the call, dragged myself up and out the door to cross the warehouse and down to shop floor. Now the warehouse is full of crates and those large trolley cages we use for moving stock into shop floor. As I came out the break room I saw a person duck behind one of said cages. I thought it was Shaun, as the shape was black (the uniforms remember), large and 100% a human. Arms, legs, a head, the whole lot. I called out hi, as Shaun is a bit of what some would call a 'lad', and would probably get offended if I strolled past without greeting him. I got no response. Peering round the cage as I walked up to it, I saw that there was no one there. I'd like to say I've never taken any kind of drugs or hallucinogenics, and at the time drunk rarely and sparsely so I couldn't have been effected by anything like that. The lights in the room were bright modern, so there was no flickering and no way could've created a shape like that. Plus they were directly overhead so it couldn't have been my own shadow, I was 100% done with being in that room. I legged it down the stairs, and got to the bottom, noting that the slow creaky door was shut tight. If anyone had somehow got down there super-fast it would've taken an age to shut.
I got out onto shop floor, and went to find my manager. I was still trying to be rational, and decided that if there was an intruder in the warehouse who had just hidden very well that that didn't look good on me for just walking past. I located him and asked where everyone was. He seemed confused, but told me that Becca was on tills, he had been in the office and Shaun was loading fruit by the front door. I had been the only person in the entire back of the shop.
So all this doesn't sound overly scary, but what keeps me from dismissing it as just a trick of my mind is how all the facts are stacked against it. I like horror and creepy things as much as the next guy, but I sleep just fine at night knowing it's all imaginary. My story is very true, I saw a figure. Not a shadowy haze, but a human mass which was there when all logic proves it can't have been, and that scares me to my very core. I'll never forget it.
