Of course, if you see the same TIME on the clock it means that it has stopped. Better put a new battery in. However, if it's an old-fashioned wind up clock you'd better wind it up. Or it could have simply broken down...maybe never to go again.
As for seeing the same number on the clock it either means you've got 'tunnel vision' and need to move your head slightly, or that you're having a dream of some sort.
Sorry, I can't help.
