Fallen-asleep definition

Her first day and she had fallen asleep on the job.

The truck driver, who was carrying a load of sound equipment for the show, had fallen asleep at the wheel and caused the deaths of two college students.

For a moment she lay waiting, and then realized he had fallen asleep.

The line down the highway blurred for a second and she realized she had nearly fallen asleep.

At first she thought it was the thunderstorm she'd fallen asleep listening to.
