Write a mysterious scene set in a dark alleyway late at night

Write a mysterious scene set in a dark alleyway late at night. The only source of light is a flickering street lamp, casting eerie shadows on the walls. In the distance, you can hear the faint sound of footsteps approaching, but you can’t see who is coming towards you. As the figure gets closer, you start to make out their features, but something about them seems off and unsettling. Just as they reach you, the street lamp goes out, enveloping you both in darkness.
