Jeff,

Does your machine have an ambient light sensor?

Light from the monitor, reflecting off of you, will often trigger changes in the amount of light the ambient light sensor is seeing.

Happens most with large changes like switching from a bright white (browser) background to a dark one, just as you describe in your symptoms.
