Each sense is equally unreliable. If you tell someone that you are about to stick their hand into a bucket of scalding water, but instead you plunge the hand into ice water, most people will cry out as if the water was hot. A mental expectation causes the sense of touch to deliver a false picture of reality. So the relationship between what you think and what you see works two ways. Your mind can misinterpret what you see or your eyes can tell your mind a false story.
