You wake up one morning to find a strange man standing in your kitchen. Worse than that he seems to have made himself completely at home.

If you suffered from the neurological disorder called "facial agnosia," a twilight-zone style experience of this sort might be a reality.
Facial agnosia typically occurs to people who have received damage to the right hemisphere of the brain due to stroke or injury.
People with facial agnosia lose the ability to recognize even the most familiar faces: in this case a husband and daughter, the president of the United States and a bust of Abraham Lincoln.
