Abandoned Building

....It was dark, cold, and damp as you enter this one-of-a-kind building. As you got in, the whole place is dim, with dead bodies and splatters of blood and strange liquids around. The furnitures and most of the rooms are dirty, filled with debris and gruesome mess. You turn back to the door, trying to open it.. but it was locked, that is, when reality struck; you're trapped and there's no way out. You hold your source of light(pick anything), knowing that nothing good is gonna happen
