Vogue: I’m sorry but I have to call shenanigans. Normal emotionally healthy BY girls do not do this, and the few that do generally have security issues, and are embarrassed enough to keep it a secret.
Having an imaginary friend sounds like a mild form of psychosis to me, which is fine as long as the friend isn’t telling you to hurt other people.
Having dolls and such is not normal for an adult and a sign of emotional underdevelopment, so it’s probably a good idea to see a professional if you are considering it. (I’m wondering if this was a joke thread?)
