YES, same thing here,, sometime growling, barking the whole time, flipping pillows off the couch and then barking at them like its their fault,, Sometimes he will run around the end table about 20 times ( hes got to get dizzy) I do just watching him! Then sometimes he get so fast and he'll get caught in the lamp cord and drag it across the room,, all scared like its chasing him!
Thats when " game over" when the lamp ends up on the floor!

LOL
