How many spiders does an average person really eat in their sleep in their lifetime and are there documented studies that proved this and if so where can the data from these studies be found?

you eat about 7-8 a yearActually it's a myth. There is no scientific or medical proof that Spiders crawl into humans mouths as they sleep. It's not 4 spiders a year and it's not a pound of spiders in a lifetime, it's just plain untrue
