如果是这样,代表什么?

我的朋友message 我,她说她很痛苦, 问我为什么会这样, 你们能告诉我为什么她会有"幻听"吗?

I can't sleep when my husband is back.

 He went to china last two weeks and stay there for 9 days. I have good night sleep for the whole week. When he's back here, my problem is start over again.

 First, i can't sleep. Every night i was sleep nearly 3 am in the morning. Sometimes, i play game and computer until late night also no use. Now is getting worst.

I sleep but i can here the sound all around me. Car crossing, people come back, even the lorry from the main road.
