Have you ever been genuinely frightened & if so, what was the source of this fear?

Okay, if it’s from watching a movie then fine, that’s fair enough. However, i’m more interested in real life experiences. Something that happened to you or maybe you were witness to. Do you scare easily or not? Did this fearful experience affect anything for you in the long term or was it more or less brushed off? Woud you say you have a fear of anything specific, perhaps even a phobia? Wow, that’s a ton of questions, aren’t I the curious one?
