Hogwarts Syndrome 

Happens after reading or watching the Harry Potter Series. An extreme sense of nostalgia or desire to be either Harry Potter, or a character within the series. Those who suffer, experience a great feeling of nostalgia, yet a lonely desire to be within the Harry Potter Universe.

John: "Damn man, I just finished the Harry Potter Series. What a ride, I felt like I was in a whole new world. In fact, I kinda wish I was in the Harry Potter world. Life is so great there".
Jack: "Nah man, you're just suffering from Hogwarts Syndrome. Every fan goes through it. Don't worry it'll go away in time."

Hogwarts syndrome 

You want to go to Hogwarts so bad it hurts. You want to be a part of the world in the Harry Potter universe, You want to be involved in the wizarding world. We all know you probably have a massive crush on one of the characters as well, and you probably ship either drarry or wolfstar.

Beanz: I am really sad I just want to be part of the wizarding world it’s not fair :(
Heinz: I think you have Hogwarts syndrome! Don’t be sad! :(
