Creators Block?

Or is there another name for it? Writers block is historically documented. But what about when you just can't be creative, when you mind is blank, empty a vacuum? When you have multiple outlets for you creativeness, you can usually switch from one to another if the idea and inspiration fails or falls short. But i'm not talking about those days when what ever you are doing is like pulling teeth, instead of flowing continuously from you. But those days when nothing flows from you, your mind is not sparking at all. The screen remains blank except for a flashing curser, the canvas remains unmarked , the paint undisturbed and the camera does not even make it out of the bag.

This for me is Creators Block
