Hi, well most probably because dreams occur within your mind and not what you see with your eyes. You can still imagine things with your eyes closed, so dreams are just the same.

We are able to see with our eyes, because light activates receptors in the eye's retina, which then send electrical signals to the brain via optic nerves.  the brain then processes these optical signals, and translates them as images.  When we dream, our eyes are not being used, but the brain experiences electrical activity, which it interprets as images constructed from stored memories.  

The analogy (imperfect as it is) would be the difference between watching a live broadcast on TV as it happens, or watching images created from a library of archived material on a DVD.  The TV in this analogy is the equivalent to the processing unit in our brains. In the first, the TV is receiving a direct real time signal through its aerial (its eyes) which it translates into images.  The latter doesn't require an aerial, but the tv is still able to form images from the information stored on the DVD (its memory).
