Just wondering if anyone else’s dogs sleepwalk.

A few minutes ago Boomer (15-wk-old AB) leapt up from his sleep barking & growling & chased something down the hallway, insisted I let him into the living room where he chased it all the way to the dining room.  And then he turned around & looked at me in confusion.  It was about 4am; nothing going on except me checking Facebook.

I know it sounds like a ghost & there have been a fair amount of odd occurrences here, but I’d rather think it was sleepwalking.
