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'.
