Taking into account the time I'd just spent napping, I'm really picking up the sense that this time's exam really won't be straight forward.

My father was taking a nap on the sofa, with his legs stretched toward the fire.

She was taking a nap the whole time.

He dozed off in history class.

He is always taking a nap at school.

He dozed off.

He dozed all the while.

His speech went on for such a long time that some people began to fall asleep.

The teacher caught the student sleeping in class.

I went to sleep during the math lesson.

During the class she fell asleep in spite of herself.

I do not allow sleeping in class.

I fall asleep in the class every now and then.

I noticed that I had slept past my station.

I was afraid I might fall asleep while driving.

Last night I began to nod off in front of the TV.

So boring was the lecture that he fell asleep.

On my way home, I fell asleep on the train and rode past my station.

Even the worthy Homer sometimes nods.

Mr Jones reprimanded me for taking a spot of shut-eye during class.
