Imagine waking up to find a strange man roaming around your home. Nicolas Cage just lived the nightmare.

TMZ has learned Robert Furo was arrested at Cage's crib in Newport Beach at 2:00 AM yesterday morning, after the actor woke up and found the guy wandering inside his digs. Sources tell us when Cage confronted the guy, he realized that the jacket Furo was wearing was actually his. Creepy!

The Orange County D.A. has just charged Furo with Burglary. He's currently being held in the OC Jail on $50,000 bail.
