Dream of

I am lying on my side in bed asleep, facing and quite close to, the edge of the bed. I then become semi-conscious because I need to roll over, but before I do, I am aware of a dog very close, almost face to face. It looks like a black german shepherd. It is just looking at me, It invokes fear enough that when I roll over I am fully awake. It is not a nice experience. I own two german shepherds, I have no fear of dogs.
