sleep on something

sleep on something idiom
Consider something overnight before deciding, as in I don't know if I want to go on such a long hike; let me sleep on it. This usage was first recorded in 1519 in the state papers of King Henry VIII: “His Grace ... said that he would sleep and dream upon the matter.”
