As a solution to dream scepticism, Ernest Sosa has argued that when we dream, we do not believe the contents of our dreams, but rather imagine them. Thus dreams do not cause false beliefs; so my beliefs cannot be false as a result of being caused by dreams. I argue that even assuming that Sosa is correct about the nature of dream experience, belief in wakefulness on these grounds is epistemically irresponsible. The proper upshot of the imagination model is to recharacterize the way we think about dream scepticism: the sceptical threat is not that we have false beliefs. So even though dreams do not involve false beliefs, they still pose a sceptical threat, which I elaborate.
