Probably not what you meant, but sometimes, before I fall asleep, I "see" bright flashes of light, as if there's a strobe light going off outside my window. Rarely, I also hear a loud "boom." Apparently it's a known sleep disorder and has the terrifying name "exploding head syndrome" https://www.sleepassociation.org/sleep-disorders/more-sleep-disorders/exploding-head-syndrome/comment-page-2/ https://www.sleepassociation.org/sleep-disorders/more-sleep-...
