I don't know. However I will entertain you with some of them.
The clogged, overflowing toilet. Speaks for itself. It's happened to all of us..
Swallowing hairs. I gag really bad whenever I find a hair in my mouth, so whenever I feel a strange tickle on my tongue, I freak out a little and rinse my mouth with water.
I guess my beloved old PC biting the bucket. The thing is like half as old as I am and still functional (and I am 24).
A fire in my home. It's never happened, but I don't know if I would panic or not. I would like to think I would douse it with water right away, but I am only human. We always think we'll be fine, but what if we're not?
My fax machine ringing, bringing more work... heh just kidding, my spine does crawl a little whenever it does ring though... I even got a paper advertisement through my fax machine once, and I didn't even know that was possible. Wasted my ink!
Getting sick/dying; I think this one comes with being human though.
I used to hate stinging insects/spiders, but I'm so sick of feeling apprehension around them that I have rage. Whenever I see them in my home I squash the little ... fuckers. If I saw a bee I would seriously punch it to death.

teach that thing to be in my home!
