 A friend of the two-model account may say that people affected in this way are to be classified differently from those engaging with fiction: their “imaginary” beliefs are not quarantined from their “real” ones. But note that the simultaneous yet distinct activation of the imaginary and reality models also accounts for the cognitive situation of agents who are somehow dissociated—subjects who experience a world of their own and still do not lose their grip on the real world. Sleepwalkers are a clear case. A sleepwalker may mobilize both the reality model, allowing her to avoid obstacles while walking, and an imaginary model, in which she represents the world she is dreaming about. Despite this, she is not engaged in make-believe (Meini &amp; Voltolini 2010).
