On average, you swallow eight spiders a year in your sleep.

Thankfully, this one's far from true. Scientific American claimed that spiders don't intentionally crawl into a bed because there's no prey and they don't care about humans. "Spiders regard us much like they'd regard a big rock," Bill Shear, former president of the American Arachnological Society told the site. If a sleeping person has their mouth open, they're likely snoring, creating vibrations that warn spiders of danger and scare them off.
