Zombie In Abandoned Asylum

Having woken up next to the dead I how no idea I found myself here, in this situation. The simplest explanation is that I too am dead. Or I was mistaken for a dead man. Hearing a terrible scream I understand that nothing good is coming for me and help is not on the way. I grab a lantern lying next to the body and see in the darkness the shadow of a dead man. So he is alive?! It's a zombie. Am I actually a zombie too? No, I'm alive. Well then, I'll try and keep it this way! The most important thing now is survival.
