S1, E9: Sam is haunted by a vision of a woman trapped in the brothers' childhood house and convinces a reluctant Dean that they need to go home. Upon arrival, they meet the woman in Sam's premonition, and she reveals that the house is haunted. The brothers discover that their father visited a psychic, Missouri Mosley (Loretta Devine - "Waiting to Exhale," "Crash"), after their mother's death, and they seek insight from the same woman. Together, the three discover that a malevolent poltergeist has inhabited the house and set out to exorcise it but are blindsided when another unseen spirit steps in.
