What exactly is this?

There's was a guy 6/7 years younger to me, I used to admire him a lot, he had this strong personality, cheerful and positive aura. Our friendship just ended in an unimaginable worst way possible. But still he was there in my mind always, I cared for him.

It has been soo long that i haven't seen him or talked to him. We're completely out of contact but still he has a strong presence in my mind. Even today I think about him before bed. I think about scenarios where we are together (imagination), i literally saw him multiple times in my dreams. I can't get over him!

I am think about meeting him soon...

Is that a right thing to do?
