On the table, while being worked on by doctors, a patient’s eyes are taped shut.
So, how is the patient reporting visual information if it’s his brain that’s ‘seeing’ these things around him?
It isn't black electrical tape they use. So, if you come up enough to have a flickering of consciousness, you will see light from the operating lights above you, hear voices and see shadowy forms.
It's like laying on a dock with your eyes closed. You can see where the sun is and if anyone comes walking by, you can see their shadow.
