End Of All Ends

This is a little short I wrote for a theatre arts class writing prompt which was only supposed to be a paragraph or two. I decided to finish it, I don't exactly remember what the prompt was but I know it had something to do with writing about a zombie apocalypse, which I thought was overdone so I made it phycological instead but still kept with the zombie post-apocalypse theme. Have a look into a dying man's head as he lives his last moments, or are they?
