What is the scariest dream you've ever had that you remember?

Mine was when I was repeating the same moments over and over for 5 times and each time I tried to change it, but the outcome always ended the same. It always ended with me being killed.and eaten by a big scary fish while trying to save my mother from the dock that broke beneath us and she'd always get eaten by another fish which always happened because she'd try to save someone else on the dock. So my thought was that she's just too heroic for her to stop being killed by a fish. So I gave up and that's when I woke up.
