Have you ever wondered why you don't see motion blur when your eyes flick to a new position? Why, if you sit in front of a mirror and watch yourself, you never see your eyes move? That is saccadic masking, one of the lies your brain tells to avoid confusing you.
Have you noticed that the first tick after glancing at a clock with a second hand can take more than one second? No, it's not just you! That's a related phenomenon called chronostasis, or more commonly the stopped clock illusion.
