空飛ぶ目覚まし時計

Many sleepers experience that after they turn off the alarm clock they go on sleeping. One thing that sometimes wakes you up at night and prevents you from sleeping is the mosquito or blowfly when flying around your room. You can't and don't want to fall asleep again until you've caught it. These produces adrenalin and requires movements. The alarm clock blowfly works like a "blowfly" that at the desire time it escapes from a cage in your room. It starts moving and producing sound around you - to turn it off you should catch it and put it back in the cage.
