Mystery story

I heard this story from my friend. I met Hae Rim, who was my friend, in

elementary school. We were very close. She was my classmate for

2 years. One day she told me “I couldn’t sleep everyday.�? At first I

thought she was very sensitive about something. Actually I couldn’t

understand her problem. She took me into her confidence, whenever she

tried to sleep. She heard very strange music. She had told this to her

family but nobody believed her. Because nobody heard strange music

except her. She looked very tired everyday and slept during lessons.

Until now I don’t understand her experience. I just guess she had had

stress a lot because of study. Her experience was very curious to me.
