When you know what anime someone is mentions or talking about, but you just can't seem to remember what anime or which anime it was.
"I can't seem to remember a certain anime that I seem to like."
"What was it about if you can remember?"
"Well it was about some high school boy finds a notebook and if he writes a person's full name down they die or something like that."
"Sounds like you have a case of animesia, Seth."
