I Am You But You Are Not Me

"Dark is not coming back, it was just a nightmare. Dark is not coming back it was just a nightmare." Mark whispered to himself over and over. Then the lights started to flicker. He heard a deep laugh in the room. The door was slammed shut. He could hear Amy on the other side of the door getting up to check on Mark. Then the lights stayed on as he looked at the mirror and saw Dark. Black mist started to trail around the edges of the walls on the ceiling. The lights then went out completely. Mark could feel the mist enter his mouth and reach inside of him. He quickly closed his mouth but it was too late. Dark was here. Mark tried to take back control but to no avail. He started to breath heavily as he leaned against the wall. Mark started to cough and hit the walls. Amy could be heard banging on the door, screaming for Mark to come out.
"Mark! Mark! Can you hear me? Mark! Open up!" Amy shouted. Mark fell onto his knees and collapsed on the ground. His eyes became heavier and heavier until his sight was replaced by darkness.

"Leave me alone!" Jack shouted as he felt onto his knees and closed his eyes tightly. Tears started to form in the corners of his eyes. Then the pain stopped. Jack opened his eyes and sat up. Then all he saw was darkness. Antiseptic had taken over Jack's body.
