Kim said in the comments on Peacebang that some brain research has found that the brain stores memories of things we see on TV the same way that they store memories of actual events.
This doesn't make a lot of sense to me.
I've seen TV shows where people get migraines. I've had migraines. The experience is really different.
I've seen "The Accused," but I don't feel like a rape victim. (Or a rapist, for that matter.)
I will admit that some scenes in books really haunt me. For whatever reason, I'm really phobic about addiction, so the scene in "A Monstrous Regiment of Women" where Mary Russell is kidnapped and injected with heroin over and over creeped me out far beyond anything I've seen on TV in years.
