Have you ever heard the idea that a person is actually a crowd inside? The problem is that they all have different personalities, beliefs, values, desires, and intentions - and they take turns being in charge. It isn't the same as multiple personality disorder (now known as dissociative identity disorder), but it does sounds like something in that direction. Most people are neurotic to some extent. This idea of a person as a crowd makes sense, doesn't it? Haven't you ever been in a strange mood that you didn't understand? Or done something that didn't make sense afterward? Or have you ever done something that just felt like it was another person entirely? Yep. The healthier you are, the more integrated these parts of yourself are and the better they work together. The worst part is that you may have other people entirely represented in yourself - someone to stand in for your mother, a teacher, your friends, people you don't like. They don't even have to be human. The pitbull and the chihuahua can be there, too.
