You were looking something up — a word you'd heard, totally innocent — and the results showed you something you didn't expect. Images, or a video, that made you feel weird and uncomfortable. You closed it fast, but you can still see it. Now you feel a bit sick, a bit ashamed, like you did something wrong, even though you weren't looking for that at all. Part of you wants to tell someone. A bigger part is worried you'll get in trouble or have your device taken away. So you say nothing, and the picture stays stuck in your head.
