Baptism, either literally or figuratively.
A common sacrament among strains of Christianity is baptism, where a person is either immersed or washed in water as part of their initiation into the Church. The person is thus washed "clean" of their past sins, and is ready to begin a new life as a Christian.
In fiction, "symbolic" baptism can be a sign of Character Development, where swimming or watery immersion marks a major turning point in the characters' life. Most commonly, it marks the point where the character begins to let go of the past, or is initiated into a new phase of their life. Sometimes such scenes are a Near-Death Experience with the character almost drowning, reinforcing the notion of spiritual rebirth.
