A person who's so lost in their own mind they think they're talking to multiple people, but it's just them being a lunatic.
A man in the park screaming, "You're not a king, you're a clown!" to his own shadow.
A kid on the bus yelling, "You're not my dad, you're my imaginary friend!" to his own backpack.
A woman at the store arguing, "You're not a goddess, you're a failure!" to her own shopping cart.
