Crabjoes bogey man in the dark thread made me think, whats your silly, potentially embarrassing irrational fear? For me; alien abduction. I think this was caused by Close Encounters of the Third Kind when I was very young (6, maybe 7 years old?). In a couple days I'm taking a solo motorcycle trip across 1600 miles and camping out while I do it. I'm not too terribly concerned about things that could actually happen, like mechanical breakdowns in the Alvord Desert, getting plowed by a semi on the I80 in SLC, or winding up in the bottom of the Flaming Gorge after swerving around a deer, but getting abducted at night while camping out in the high desert, that scares the poop out of me.
