I woke up with these marks on my hand - I can only imagine the look in that spider's eye's as he chomped down on my hand (that rests very, very close to my face as I sleep!) No sign of him that morning so Sky informed me that I do sleep with my mouth open. Well, you know what they say - the average person swallows about 700 spiders in a lifetime. (Heard it on a radio show - but gross, huh?)
