A sadness or depression at the fact of not being able to live in a fictional world usually presented in a film, video game or book. It was given a name after the release of James Cameron's Avatar when a large amount of people expressed this feeling going as far as to say they are suicidal on internet forums. This phenomenon would later go on to inspire the creation of the Reality Shifting TikTok trend (Which is just dreaming, despite what the 14 year old girls would want you to believe.)
James: I'm really depressed after reading Harry Potter. I want to live in that world so bad.
Cameron: Well James, what you're feeling is Post-Avatar Depression. It'll go away in a few weeks.
Cameron: Well James, what you're feeling is Post-Avatar Depression. It'll go away in a few weeks.
