Mental time travel.

When you were a child, were you ever bitten by a dog?
If so, take a moment to recall as much as you can about that event. Can you see the surroundings?
What did the dog look like, and how did it come to bite you? Do you remember sounds, such as the dog snarling or yourself screaming?

Autobiographical reminiscence can be described as mental time travel, with the rememberer transported into the past to re-experience, albeit only partially, a moment of his or her personal history...
