My father had died I had to drain some fluid from around his shoulder. I made a few incisions then started sewing them back up, I noticed his leg moving, then it happened again and I heard him breathing and was thinking that I would have to explain to him why he was waking up in a mortuary. I mentionned it to my wife. Then all the dead bodies in the mortuary started waking up.
I was being followed by lots of zombies. I jumped down onto a roof to escape. Someone handed me a gun, then I came across a zombie walking towards me. I tried using the gun, it didn't fire. I then put it directly to the zombies head, but again it didn't fire. the zombie seemed more like a real person and actually quite nice and I realised that he was in pain and wanted me to shoot him.
