In a dream, you are always yourself in the most absurd arenas. When you wake up, your mind will clear up and the absurdities will disappear. You are both conscious & aware of your surroundings again.
In unconsciousness (e.g. anesthesia), no memory traces are stored. In a wake up, you immediately relate your perceptions to a memory compilation of your most recent traces with certain more distant – but essential – ones.
