Unseen

It's dark outside I'm walking down the street and hear footsteps behind me. I turn around to see who's there, only to find no one. I shrug it off and turn back around. I get this gut feeling to run, but I just stay at my pace and ignore it. I think to myself it's all in my head. Suddenly, this bulky arm wraps tightly around my neck, and I hear a deep malevolent laugh directly behind me. I try to scream, but it's too late. He covers my mouth. My lungs feel like they're on fire. I try to fight him, but I barely make a scratch. I start to feel incredibly dizzy, and my lungs feel like they are going to explode. Everything begins to fade into darkness.
