I can understand if you are travelling away from a light source faster than light can travel, you can only see darkness, but out in our galaxy or universe, there is plenty of light sources in every which direction. Would it still be complete darkness, or will it be blinding light?
For example, you have water flowing down a river and an empty can. If that empty can is moving against the water faster than the water is flowing against it, the water doesn’t stop existing, but more flows in faster than it would otherwise. I am terrible at explaining things, I don’t know if I said what I meant properly.

Using your can analogy, the light that has just bounced off you, you have just ‘ran into’ with your eye. Can you see yourself in the past?
The speed of light isn’t about light, but the fastest anything can travel in the universe. When you pick up a stick, does the whole thing move up at once? Or does the end you grab move up first and pull the rest of the stuck up in a kind of wave? If things move faster than the speed of light then you could pick up the stick but the other end moves up before your hand does. Breaking the speed of light breaks causality and causes you to move backwards through time and is also probably, almost definitely, impossible.
