It might just be a healthy imagination, but I've struggled all my life to not confuse fiction with reality.
It's part of why I don't watch much TV. Rationally, I know that it's just actor on film with some pretty good special effects, but there's a part of my brain that I keep catching trying to see things I know are fictional as real.
I'm not sure if this is AS-related or not. It's probably a problem with taking things literally. We trust our senses to tell us about the world around us, but television and movies exploit this to create illusions to carry us into a story (in ways you just can't do on a stage in a theater). If your brain interprets all input as real, your rational mind has to deconstruct what you see to realize it's not "real."
