sleep lightly

I sleep lightly, as do all old men; but last night I slept unwaking till broad day.

I was uneasy and could not sleep,—good captains sleep lightly, child,—so I came on deck about two bells in the mid-watch.

The stout farmer was soon on foot—men sleep lightly in these troublous times—proffering food, fire, and shelter.

Instantly the sleepers awoke, for those who are in the midst of danger sleep lightly.

Strike near and ease the fall, there are those who sleep lightly here.
