A southern Illinois man awakened to find a spider in his bed, and in a panic, ran through a glass door outside his home, police told FoxNews.com.

The man's identity was not released, but the 20-year-old was apparently sleeping in the buff when he spotted the spider Tuesday morning in his bed, Mike Judge, the police chief, said. He apparently ran through a glass storm door during his escape, cutting his arms, legs and a finger. He was treated at a hospital.

Authorities fielded numerous reports of a bloody streaker and later found the man back at his home, where he'd donned some shorts.

It isn't clear what kind of spider he encountered.

The sheriff doesn't suspect drugs or alcohol were involved.
