Night hiccups

It was 3:30 in the middle of the night. I was in a dream which was rather happy one though I've forgotten what it was like. Suddenly I was waked up from the dream world to the real because of a funny but serious reason. I got hiccups in a sleep for the first time in my life. I was so sleepy that I tried to keep lying in my bed at first but I couldn't do it. The hiccups got more strenuous and frequent. I got up at last and had to struggle to stop them almost for an hour. I remembered a news topic regarding hiccups in the last few days. It said that a doctor who put his finger on a cure for hiccups got the IgNobel Prize. It might sound funny but hiccups can be sometimes critical in case of an operation under general anesthesia for instance.
