daydreaming...wickapedia has "maladaptive daydreaming" meaning your daydreams influence how you live your life or you get physical reactions to the dreams...also Fantasy Prone Personality.
personally I think these concepts have implications to psychosis or appearing psychoitic especially since you can lose sleep with daydreaming and depicting daydreams to a psychiatrist may come accross as hallucinationsi, depends on how vivid it is and whether you detach ownership for what is going on maybe thinking it is telepathy or something real when it is just a dream
