The human eyes are astonishing. Whether we realize it or not, they possess the power to constantly break the average perception of our surroundings.
Take, for example, the chronostasis effect. It occurs as an illusion in which we believe that time has stopped. If we stare at an analogue clock and we focus on the second hand, it appears that it freezes for a moment. During that moment our brains register a false memory, according to which we’ve been staring at the clock for more than just a second. This actually makes our brains stretch the perception of the time that has passed. In other words, we believe that the second actually had been more than just one second.
Similar illusion occurs with the ringing tones during a phone call. We believe that the first pause between the dialing tones is longer than the subsequent ones. Lengthening the time perception is a common thing, but we rarely notice it.
However, it’s all just an illusion. Time doesn’t “stop”, it just follows its average flow.
