You were a human used for hellish experiments. The lab was burnt down but you were still there barely alive. You had charcoal smeared on you, you were chained to the wall and you were bloody and dark..

Dream had heard of growling near there so he went to check it out. He went inside the lab and he went to the basement, the basement was in perfect condition. The cells empty except one.. He went to the last cell that wasn't unlocked, the cell was chained for it to not open.. Then he saw.. you.. you snarled in panic trying to get out of your chains but you couldn't.. Dream could tell you were just scared.. But he could also tell you genuinely not control your body.
