Things like games or movies don’t do it because I expect it. Sudden, unexpected loud noises in the real world will do it though. Once I was at my dad’s place and he started cooking, but he turned on the wrong burner on the stove - the burner he turned on actually has a glass serving bowl on it. After a while it started to hiss and I realized what was happening, and I tried to quickly reach the stove and turn it off, but the bowl suddenly shattered into a thousand little pieces. Basically exploded. That did it. I had an episode on the spot.
