The shop had closed and I was alone, finishing some cleaning work. As I was working in the back, near the antique furniture, I began to hear soft, shuffling footsteps, as if someone was walking slowly down the aisle.
I thought it might be one of my colleagues, but when I stepped out into the hallway, there was no one there. I tried to ignore it and carry on with my work, but the sounds intensified, as if someone was moving between the shelves. I decided to check the doors to make sure they were securely closed.
When I returned, I saw something that froze me. In the corner, near a display case, there was a blurred reflection of what looked like a human figure, but it disappeared instantly as I approached.
I felt a cold chill run down my back and a bad feeling. I quickly gathered my things and left, but from then on, I was never left alone in that shop again after closing time.
The feeling of an invisible presence, the unexplained sounds and the sudden disappearance of the figure left me uneasy. Although I failed to discover the truth behind these events, I preferred to keep any possible supernatural encounters at bay.
