answer:There is probably some light coming in from outside. When you turn off the lights it might appear pitch dark, but as your eyes adjust, if you cam see, there is light coming from somewhere. Does that happen when you wake in the middle of the night? You can see somewhat? And then if you ut on the light amd turn it off again it is pitch dark for you again, and you can’t see as well as when you first woke? Or, can’t see at all?
