　　Insomnia(失眠)

　　I just could not fall asleep the other night. I just didn't feel sleepy. I can't explain why, but it was really annoying.

　　I got very bored lying in bed, so I decided to read a book.（ 26 ）But even when I finished reading, I still didn't feel tired. So I listened to some peaceful music. That didn't work, either. I have heard people say if you have a warm drink before bedtime, it will help you drift off to sleep. So I went downstairs and made myself a cup of tea. （ 27 ）Still, I couldn't sleep. I was getting very frustrated by this point!

　　It felt strange to be awake while everyone else was asleep.（ 28 ）In fact, it was a little big frightening. When you go to sleep, it feels like one day ends and another begins. But if you stay up late, you realize that day and night are just a gentle transition(轉變), a cycle while has no end and no beginning. At 4 a.m., I noticed a faint light coming through my curtains. The sun had started to rise!

　　Normally, I'm a heavy sleeper.（ 29 ）So on this occasion, I consider myself lucky to see a beautiful sunrise. I knew I needed to get some rest, but it seemed the harder I tried to force myself asleep, the more difficult it was.

Eventually, I just let my mind go free. （ 30 ）I listened to the birdsong... and the next thing I knew it was 11 a.m.! I was happy that I had managed to get some sleep! I have never struggled with sleeping before, so this was my first experience of insomnia. Fortunately, I have been sleeping well since then.
