I had a dream wherein I'm in the bathroom having a shower and when I open the shower curtain there is a big dog in the bathroom with me. The dog is black and brown, and I'm 80% certain it is a rottweiler. When I first see the dog, it was not being mean but I was immediately scared because of the appearance of the dog. I am a dog lover myself and own four small dogs, but I've always had a fear of big and ferocious dog (like rottweilers). So a face-to-face encounter with such immediately elicits fear in me. When I first open the shower curtain the dog is just there sitting looking at me. It was not being mean but not necessarily being friendly either. But when I tried to move (I think I was trying to reach for a towel) that's when the dog starts barking and snarling at me. So I'm just there paralyzed with fear and unable to move. What can that mean?
