I sleep for 8 hours every night.

I have a headache due to lack of sleep.

In the old days, people said 'Nenu,' which meant 'to sleep,' as we say today.

In the old days, people went to bed when night came.

You need a sleeping bag when you sleep in the mountains.

I will sleep now.

I go to drink coffee in front of the station every day.

I used to live in Tokyo before.

I remember talking to him before.

Please sit in this seat.
