I don't know if this counts, but when I was 15, I once had a high fever. I had this dream about zombie apocalypse, and when I woke up, I didn't realize that it was just a dream, partly thanks to the fever. So when I started to barricade our front door, my parents woke up wondering what the f***s going on.
It didnt last a few seconds, but still.
