NO, People Do Not Swallow 8 Spiders a Year While Sleeping. “Luckily for all of us, the ‘fact’ that people swallow eight spiders in their sleep yearly isn’t true. Not even close. The myth flies in the face of both spider and human biology, which makes it highly unlikely that a spider would ever end up in your mouth.”

Anyone who repeats the “fact” that people are regularly swallowing spiders while asleep clearly hasn’t thought about it. The instinct to crawl into a gaping mouth and be swallowed is a trait that would have been selected out of spiders by now.
