--Okay, so the whole statistic that says "Spiders [or other insects] crawl in our mouths while we sleep at least twice [or more or less] a year." What? Do we know that? How do we know that? How on EARTH can that be tested? Who tested that? Who wanted to be that subject? I just find it hard to believe that we can even know something like that--ESPECIALLY, if it wasn't tested objectively. We're ASLEEP.
Just after I type this, snopes comes to mind.
