We live somewhat "out in the country", and my parents found a SNAKE in their bedroom at like 1AM once... my dad and I took care of it though, and my big brother was squealing the entire time. I laughed. Anyways, I've found spiders in bed before, so I always check in my pillowcase and on the sheets before I get into bed. It's worth the look. The only spiders we have in our house are fiddle-backs... they're posionous.
