Have you ever taken a train with some friends. You were chatting happily for a short while and then you look up at the train signal – OMG! You have missed the station.
You thought you were in the conversation for only a short while but in reality, an hour could have passed. This is a result of you being too immersed in the chats that it makes the time flies.
This time distortion is an aspect of hypnosis. It happens to us commonly.
