When a bulb is turned on, it emits millions of photons(a fundamental particle of visible light) which is scattered in all directions. This photons that is emitted hits every object that comes in it's path. This objects absorbs majority of the photons striking them also reflecting a fraction. This light is then reflected back to our eyes which helps us to see objects.
As long as the bulb is turned on the room will have a constant supply of photons hence illuminating objects in a room. However, the moment the bulb is turned off things changes rapidly. As no new photons is emitted so there is no new photons to be absorbed and reflected by objects in a certain room. Which means complete darkness.
Darkness is just the absence of photons, so don't be afraid of it.
