O.k I'm not sure how quite to describe this experience, but I'll try my best.

The other day, I was driving along, kind of zoning out when suddenly a memory hit me. It was a vivid memory about a rejection and suddenly I felt this feeling I can never describe (not anger, shame? perhaps but I don't feel it's quite that), and I just hit the accelerator really hard. That was actually pretty dangerous.

I've been sort of engaging in this kind of reflex arc for at least a decade and it's been getting more frequent. If a random memory hits me while I'm running I'll just start sprinting really hard. If it hits me while I'm reading I'll just suddenly shout out something in a really goofy voice. These behaviours are usually harmless but I'm really scared I might do something stupid while I'm driving.

Anyone with similar experiences and how do you get it under control?
