According to the Vagabond, Zoë Castillo is a 'Dreamer', but what this means has not been spelled out. Certainly Zoë's dreams are powerful, strong enough to confuse Alvin Peats, who cannot read them, and she is capable of projecting a 'dream presence' in Arcadia that is physical and tangible - very like April Ryan's initial forays in Arcadia. Faith, who seems to have a similar ability to Zoë, describes it as 'dreaming things true'.
