Why is my energy saver (spiral) light bulb flickering even after the light is turned off?

After I turn the light off, the light bulb is flickering. It has never done this before!!!

The light is in my daughter's room. I unscrewed the light bulb and I am afraid to put it back in.

More importantly - IS THIS A FIRE HAZARD???????????????

Update: Thumbs down not from me - sorry!!!!
