The old cat drowses in the sunlight on the windowsill.

She drowsed in the back row of the lecture hall until the bell rang.

A sudden drowse settled over the classroom during the warm afternoon.

She would sometimes drowse during the late afternoon meeting, her head nodding and her thoughts wandering.

During the long meeting I found myself drowsing in my chair, struggling to keep my eyes open.

Her drowsing on the long train ride caused her to miss her stop.

During the long lecture, his repeated drowsings were hard to hide.
