After Darkness (1985)

To salve his guilty conscience, an elder brother removes his disturbed younger sibling from a mental institution after a suicide attempt, and tries to bring him back to mental competency through one on one contact. Free of the institution, he continues to be haunted by dreams of a lost twin, and chants the eerie phrase "Do I stand before the King?" It is the elder brother that seems doomed to lose himself in his brother's insanity.
