Other wise for many the original spark out can pave the way to you going out to it a touch easier the next time around and so on and so forth. Our cells have a memory as does the shut down process and also the fight or flight process . If it helped us to survive a bad situation once, its not unheard of in some situations (Not always fighting) to automatically and subconsciously head for the shut down mode the next time around.
That's interesting stuff and I think it's basically like that, like a primal 'play dead' shut down feature. I think seeing the punch coming has a LOT to do with how that works out too.

Good question Vintage
