Into a monster

 One day, Err, I mean night. You were having a nightmare about monsters. Which made you wake up very early in the morning. You were exhausted and went to brush your teeth. Right, when you picked up your brush you see it. In the mirror. Two tiny horns popping out of your head. You were terrified. So you wore a cap to cover the horns. And expected it to go by tomorrow. You had slept and the next day you saw in the mirror the two horns were bigger and you had fangs and more hair. You were even more terrified than yesterday. So you chopped off the excess hair and wore a hat to cover the horns and wore a mask to cover your fangs. After a few days, all the monstrous looks were going. But at the end of the month the horns, fangs, and hair were back. This time even worse. The horns were bigger, the fangs were sharper and the hair was now fur, all over your body. You just turned into a monster.
