Why does Paul keep showing up in our dreams?

The scene is clear in my head: a crow—a large bird, which could have been an eagle—swoops down on Paul and kills him. Paul looks at me helplessly in the kitchen, where it happens. I shoo the bird away, but I'm too late. Paul's blood coats the floor. I awoke in cold sweat until I realized it was all a dream.

A similar incident happened in Manong's dreams. Paul is captured and taken to the dog pound. Manong rushes to save him from execution. 

Manong, now in Scandinavia, but who was Paul's primary dog walker, also told me a happy dream about Paul playing in the snow. 

Why does Paul keep showing up in our dreams? 

When I made coffee this morning, Paul was lying on the living room carpet, perfectly safe from birds that might try to kill him. 

A few months ago, Paul charmed Mich, who visited from Manila/Japan, into giving him a belly rub. 

He befriends birds and frogs that visit our home and only really despises Victor, the dog who lives two streets away. Otherwise, friends and family seem to like him. The neighborhood kids rush to him to stroke his head. I overheard a girl telling another scared girl, "He doesn't bite! Just call his name."
