Ernest Sosa has argued that the solution to dream scepticism lies in an understanding of dreams as imaginative experiences – when we dream, on this suggestion, we do not believe the contents of our dreams, but rather imagine them. Sosa rebuts scepticism thus: dreams don’t cause false beliefs, so my beliefs cannot be false, having been caused by dreams. I argue that, even assuming that Sosa is correct about the nature of dreaming, belief in wakefulness on these grounds is epistemically irresponsible. The proper upshot of the imagination model, I suggest, is to recharacterize the way we think about dream scepticism: the sceptical threat is not, after all, that we have false beliefs. So even though dreams don’t involve false beliefs, they still pose a sceptical threat, which I elaborate.
