[Our brain deceives us]

The brain does not "objectively" reflect outer reality, but rather what is necessary in order to survive and adapt to the environment. The "phi" phenomenon, the eye's blind spot and cryptomnesia, reflect the brain's capacity to invent information. In split-brain patients, research has shown how one hemisphere, when it lacks certain information, invents a plausible story to explain the behaviour of the other hemisphere. All this would suggest that the brain deceives us, producing occurrences which in reality have never happened, in such a way that, for the brain, convenient reality and "objective" reality are two very different things.
