how many spiders do you eat in your sleep

The widely circulated belief that people swallow an average of eight spiders per year in their sleep is actually a myth with no scientific basis. Spiders generally avoid humans because of vibrations caused by breathing, heartbeat, and movement during sleep, which frighten them away. It is extremely unlikely a spider would crawl into a sleeping person's mouth, and there is no documented case or credible evidence supporting this claim. The idea likely originated as a fabricated urban legend meant to illustrate how misinformation can spread online. Thus, people do not eat spiders in their sleep to any significant or measurable extent.
