Fantasy
Some characters cannot accept the real world, so they transpose themselves into an illusory world instead. The scope and degree of this fantasy varies considerably. A character may hold conversations with characters who aren't' there, or hear "voices from the gods" commanding him to carry out a wide range of acts. he may also interact with people and institutions of his world in an almost normal manner but with his perception of events skewed by his fantasy.
For example, a Cainite may regard himself as Lancelot from the Arthurian legends, on a quest to slay a vile demon or rescue a fair princess. Such fantasies manifest as a quirky outlook, but they are rarely dangerous (unless the Cainite believes that he can walk about in the daylight...). They can, however, adversely affect the character's reaction to others, perhaps making them more likely to frenzy ("They are Mordred's get, milord!) or determine to cary out a mad assult ("The grail lies this way!")
