Chuck Klosterman said this quote

Every night, we’re all having multiple metaphysical experiences, wholly constructed by our subconscious. Almost one-third of our lives happens inside surreal mental projections we create without trying. A handful of highly specific dreams, such as slowly losing one’s teeth, are experienced unilaterally by unrelated people in unconnected cultures. But these events are so personal and inscrutable that we’ve stopped trying to figure out what they mean.
