Two things that shouldn't have to happen, but when they happen, they should never be in the same week:
1. Killing a spider that crawled on your eyelid. (YES! EYE. LID.) Finding a spider in your room is bad enough; finding a spider in your bed is grounds for burning down your house. BUT having a spider somehow manage to jump (because really- you'd think someone could feel a thing crawling in their face) from the window sill (maybe) to your face is traumatizing at best.
2. Developing a cold where you will inevitably be a mouth-breather all night because there is absolutely no clear airway through your nose.
See the problem? That statistic that says we eat 8 spiders a year, or something along those lines, no longer seems so far fetched.
