Actually, the 2nd verse of an Anglican hymn for the evening prayer worship (compline).

To you before the close of day, Creator of all things we pray
that in your constant clemency our guard and keeper you would be.

Save us from troubled, restless sleep, from all ill dreams your children keep;
so calm our minds that fears may cease and rested bodies wake in peace.

A healthy life we ask of you, the fire of love in us renew, and when the dawn
new light will bring, your praise and glory we shall sing.

Almighty Father hear our cry through Jesus Christ, our Lord Most High,
whom with the Spirit we adore, forever and for evermore.

I pray the second stanza when I have trouble sleeping.

Save us from troubled, restless sleep, from all ill dreams your children keep;
so calm our minds that fears may cease and rested bodies wake in peace.
