6. The Capgras Daydream
Ever thought that a person you know and are close to has been secretly replaced by an imposter. That is exactly how patients suffering from the Capgras Daydream feel like. They feel as if an acquaintance, friend or a family member has been replaced by someone having very close resemblance to them. This is more commonly seen in people with schizophrenia and individuals with varying degrees of brain damage.
