What's that tickle?

An hour ago I layed down on the couch for a nap while the kids were sleeping and something kept tickling my ear. I kept brushing it away and then it would come back. Almost as if someone was tickling my ear with a feather. I eventually just ignored it and went to sleep. And just a moment ago I was running my fingers through my hair because something was tickling me and it was a big BUG!! Now I don't know where it went as I tried to get it out. Hopefully it's not crawling around in my shirt! I've got the creepy crawlys now. I hope the little bugger enjoyed taking a nap with me.
