"Te lucis ante terminum": A prayer to help you fall asleep peacefully

To Thee before the close of day, Creator of the world, we pray That, with Thy wonted favor, Thou Wouldst be our guard and keeper now. From all ill dreams defend our eyes, From nightly fears and fantasies; Tread under foot our ghostly foe, That spot of sin we may not know. O Father, that we ask be done, Through Jesus Christ, Thine only Son, Who, with the Holy Ghost and Thee, Doth live and reign eternally. Amen.
