" The dream has a very striking way of dealing with the category of opposites and contradictions. This is simply disregarded. To the dream 'No' does not seem to exist. In particular, it prefers to draw opposites together into a unity or to represent them as one. Indeed, it also takes the liberty of representing some random element by its wished-for opposite, so that at first one cannot tell which of the possible poles is meant positively or negatively in the dream-thoughts. "
