"Get your head out of the clouds and focus!"
"Daydreaming isn't going to do you any good."
"You need to stop daydreaming and start thinking."
I get this a lot. Really, anyone who daydreams excessively would. And I understand why people would say this, what with you staring out into space just like that. But there are good parts to daydreaming too.
But lets start with the bad parts. Daydreamers (excessive ones) tend to be unfocused, always drifting off somewhere. You end up becoming somewhat careless and ignorant in some cases, and tend to stay away from discussions so you can daydream. You don't always focus on the matter at hand.
That was short. Now here is the nice long list for the good parts.
Daydreaming is a really good way to think of new ideas for projects, essays, comics, drawings, researches, etc. You can broaden your thought selection by daydreaming daily. It can also keep one entertained, like me. A form of daydreaming allows you to basically play a movie in your head. This movie can go in whichever direction you want, end however you want, start however you want, and contain whatever you want. Another thing is it limits the amount of nightmares you have. If you daydream before falling asleep, your brain will dream according to the daydream or a similar dream. Daydreaming also is a way to exert stress, anger, and other emotion, and calms one down (if not too much).
I daydream daily, almost even hourly, and I can't remember the last time I had a nightmare. I am extremely introverted, I never show my true emotions even around family, so I exert my stock of emotions through art and, of course, daydreaming. On the other hand, my brother, lacks the ability to daydream (how??? how does one not daydream???). He is emotionally volatile, hysterical sometimes, and when he sleeps, he either has no dreams at all or has nightmares.
Okay, sorry for the essay on the good and bad points of daydreaming, I just needed to vent on it. /shrug
