Dream

This night that passed, I had a dream. I dreamt about a friend I use to have. 

A good friend, I use to have, when I lived in Sweden. He visited when I moved to Prague as well. 

The last thing we did, was to leave in some kind of anger, or disappointment or something like that. 

And we haven't talked since. 

And this night that passed I dreamt. And woke up with such a weird feeling. A feeling of missing. A feeling that I did wrong. That why was I so stupid, and let a good friend go. 

And I can not really shake it of me, this feeling. 

Why do we do that? people that are important and good influence on us? 

Can you "turn back time" and go back to being friends?
