I’m totally with you and I get it, and the previous commenter could have written in a kinder tone, but

imaginary friends are a mental health disorder in anyone claiming they are real.

I don’t think therapists usually encourage their patients to claim they actually got the advice from Einstein or Darth Vader or whomever. And I can give them the benefit of the doubt and assume they meant “adults” rather than “humans” when they said people.
