This 1941 tune has been recorded by numerous artists, including Coltrane and Kenny Barron.

The original title in Spanish was Duerme, which literally means "he sleeps," but can be interpreted as "dreaming."

Lead sheets are available in several fake books. The version in the old Real Book Volume Three is in 3/4 time.

This is my own Latin/Swing version, with new harmonies.
