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.

You can’t travel faster than light. In fact, from your perspective, light always appears to be moving at its full speed *relative to you*.
As you approach light speed, light coming from behind you gets redshifted, and light in front of you gets blueshifted. They would both become invisible to the human eye eventually, leaving you with only the light coming from just the right angle range for it to remain visible.
