Chased Narrow Alleyway: Facing the Shadow Self Meaning & Interpretation

"I was running down a narrow, dimly lit alleyway at night, my breath coming in short, ragged gasps. Behind me, the heavy sound of fast footsteps echoed against the damp brick walls, getting closer with every passing second. I didn't know who or what was following me, but I knew I couldn't stop. I pushed my legs to move faster, but my body felt strangely heavy, like I was trying to sprint through deep water. Every time I looked back over my shoulder, the shadowy figure gained on me, its dark outline stretching long and terrifying across the wet pavement. My heart pounded violently against my ribs as I searched frantically for an open door or a way out. I made a sharp turn into another lane, only to hit a massive, dead-end wall. Trapped, I spun around and backed up against the cold bricks, staring into the darkness as the heavy footsteps stopped right in front of me. I stood frozen, completely overwhelmed by terror as a looming shadow stepped into the dim light."
