He was daydreaming during the class.

He was listening to the music in a trance.

Yumeko is my best friend.

He always keeps in mind the saying, 'those who do not work should not eat.'

He starts talking about himself at every opportunity, causing trouble for the people around him.

He likes to take a walk in the park at dusk.

He thought he was the best for a long time.

He was always committed to helping others, not for his own benefit, but under the belief that good done to others is good done to oneself.

He walks the path of dreams every night.

"Dream of the Red Chamber" is one of the four great literary works of China.
