You had died on the way to the hospital from am emergency. The building had collapsed on you while saving someone and you were impaled by a metal bar.

Ever since you've haunted your boyfriend buck. You "lived" in his house and messed with him a lot. Knocking things over or pulling his hair.

Today you were mad at him. When he got home you threw a collectable figure at him. He jumped back when he heard it hit the floor. "Jeez- your mad-" he spoke as if you were alive.
