There are two possibilities here: Either he is becoming senile and his behavior is evidence of that. Or, he's seeing something that you are not.
Being a dog lover, I've had experience with both. Years ago, a 5 year old Westie that I had started acting weird: hiding constantly, shaking when
there was nothing there to frighten him, and following me around the house wherever I went. It turned out he had a mental disorder and he ended up
dying a few days later from a grand mal seizure.
More recently, my dog Duncan AND my dog Duff have been staring at 'things' that I can't see. I'll be lying in my bed at night and I'll notice
that both dogs are staring into the other side of the bedroom, their heads moving as if following something with their eyes...
So in the first instance, the dog's behavior was because he was sick, and in the second... Well, I think they are actually seeing something that I'm
unable to see.
Animals are neat like that.
