Déjà vu may occur when:
      a.   cues in the present context overlap with those from the past, so there is an eerie experience of having    been there before.
      b.   a lack of retrieval cues prevents recalling the time and the details of the last time we were in a location.
      c.   a memory is encoded during a peak of high emotion and then forgotten until the emotional arousal    is once again high.
      d.   repressed information threatens to enter consciousness when cues in the present activate unconscious
         memories.
