When I read stuff, a voice pops into my head (with appropriate accent) that "reads" the text to me.
For instance, take a look at the MEME thread. "RED SAUCE WITH MY PA-STA." Now, I've seen the movie, and I know the dude's accent. So I literally "hear" the guy saying that.
Or, for instance, take:
I listen to music. Then I take the headphones off, but I can still hear the tune in my head.
I don't know if this is a good thing or not, or what's going on, but perhaps someone else gets the same thing?
