I'm not sure if there's a lesson to be gleaned from this . . . other than maybe you shouldn't sleep TOTALLY NUDE.  Because there's an outside chance THIS could happen to you.

On Tuesday morning, a 20-year-old man from Albion, Illinois was asleep in bed, naked.  He woke up and saw a spider in his bed.  And he FREAKED OUT.

Still half-asleep, he jumped up and sprinted out of the house.  He was groggy enough that he didn't notice his GLASS DOOR was still CLOSED . . . so he plowed right through it.  Then he kept on running through town, naked and bleeding.

The cops got a few calls about a guy streaking and they tracked him down.

A spokesman says they don't believe there was any alcohol or drugs involved . . . just a tired guy who freaked out when he saw a spider.

The man was treated for several cuts to his body from running through the glass door.  He's not looking at any criminal charges.
