Night Vision

Night Vision is a screamer flash. It tells you to look for a hidden ghost in each picture it tells you to crank up your speakers and turn out the lights. After randomly looking a few times (supposedly with night vision), either nothing will happen, or randomly a girl with her face blurred out appears and screams.
