Dreaming about a cyclops usually symbolizes bad, limited thinking and tunnel vision. It could mean that you’re seeing things in a monomaniacal light. You have tunnel vision or your narrow minded thinking leads you to judge actions as if they are good or bad without further analyzing them.
Also, seeing a cyclops in a dream symbolizes that they are working towards their own goals with blinders on, and never taking their eyes off what is ahead of them nor getting distracted by exciting new things.
