schizotypal personality disorder

 
a personality disorder characterized by a pattern of social and interpersonal deficits with eccentricities of behavior, thought, and speech. People with schizotypal personalities may exhibit magical thinking, for example, claiming that they are clairvoyant or telepathic, may have recurrent illusions, or may exhibit derealization. Their speech is marked by vagueness, metaphors, odd usages of words, and other features that can make it difficult to understand. Persons with this disorder often are aloof and socially isolated with little capability or desire for close relationships, excessive social anxiety, suspiciousness, and disturbed affect. Although the disorder is related to schizophrenia, it differs in that any periods of psychosis are only transient.
