One of these scared the heck out of me as a kid. I had just gone to bed and was staring up at the ceiling and a small ball of intense light with crackling tendrils around it flared in the middle of the room and was gone. I ran out and got my parents, and I was so obviously scared my Dad eventually climbed into the attic above my room and reported a burning smell in the air but couldn't find anything out of place.
