Dr. King is a doctor that treated Nancy Thompson when her mother began to worry about her lack of sleep and nightmares. However, Nancy only had intentions of asking him if they could give her drugs that'd prevent her from dreaming. However, Dr. King protested, saying everyone needed to dream. The experiment gave Nancy more information than she planned as the next nightmare she had with Freddy. She discovered she could bring things out of her dream, such as his hat.
