One of the most tiring job you do while sleeping is unintentionally dreaming
I am not talking about the ones which helps you to reach the height of success and you see them open eyes. I am talking about the one in which you start running inside your school because there's a monster behind.
I told a dream as a job which is the most tiring because whenever I get dreams , it is sure that I will not wake up early the next morning.
I usually get really unique ones where I will be fighting with an unexpected person for cakes and ice creams . These are the wierd things that happens to me after someone says 'sweet dreams'.
