Are Amnesia players adults or teens?

Even so, it is not that surprising. After only 30 seconds of looking at an image your brain stores a very vivid copy of that same image that you can peruse for around 5-10 minutes. Now imagine looking at a collection of horrifying images, coupled with feelings of intense emotional stress for hours right before bed. Those images are going to be literally burned into your inner eye the entire night. Since the brain is designed to remember things that are threatening, seeing those images constantly reminds the brain of what you felt when you saw them. Ergo, the game continues even after you stop playing it. It doesn't really matter if you have an actual nightmare, not being able to sleep due to fear is a metaphorical nightmare in and of itself.

Wow, this was very educational.
