Dean was killing someone in the forest next to a lake
After he finished his mission, he threw the body into the water and looked at the lake a little but he heard a voice said "Find me", this voice turned into his head

he started walking again to get away from there but this voice was still there so he turned around one last time towards the lake and saw the water making bubbles, his instinct was sure that it was not the body that he had thrown

he goes towards the bubbles and swims until he dives his head under the water and sees the body of a woman, he immediately swims towards her and comes out of the water with this person in his arms

he gets out of the water and gently places her on the ground before doing mouth to mouth (this girl was you)
