Utterly motionless slumber
Dead sleep is an extremely deep, heavy sleep from which a person is difficult to rouse.
Someone in a dead sleep is so thoroughly unconscious that they may not respond to noise, touch, or other disturbances that would normally wake them.
I was in a dead sleep when the phone rang and didn't hear it.
