Two people were running away from someone or something. They seem to be a couple. They were running through rooms in darkness. They were near an elevator, one was knocked out and the other taken in to the elevator. The one that was just in the elevator got out and waited by the elevator. A while later, the one that got knocked out came out of the elevator. Their memories were erased in the elevator but they seem to remember knowing each other.
