I was once suddenly awoken in the middle of the night by a loud buzzing noise and a bright white light strobing past my windows. In that moment I was convinced that aliens were not only real but that I was about to be abducted. I came to my senses a few minutes later, but the sheer terror I had felt managed to make sleep impossible for the rest of the night. To this day I had no idea what it was, just that it lasted several seconds. Best theory I have was that it was a mosquito truck.
