13 Times Sam and Dean Have Actually Died on Supernatural

Dean and Sam are called in to investigate a series of near-death experiences and, as always, figure out that an evil entity is behind it. With the help of Pamela Barnes, they die, become spirits, and enter the astral plane. Along the way, the brothers are aided by their friend Tessa, who awakens Dean's memories of her with a kiss. They end up saving the day, but Sam also learns that his powers aren't exactly pure.
