"In Dreams" is a song composed and sung by singer Roy Orbison. An operatic rock ballad of lost love, it was released as a single on Monument Records in February 1963.

The song has a unique through-composed structure in seven movements in which Orbison sings through two octaves, beyond the range of most rock singers.
