Those kinds of after effect aren't indicative of harm being caused. If you do anything intense/stressful/emotional for a while then take some quiet time, your brain will take the opportunity to process what you've been up to and archive it away. TV watching in general is too passive to encourage those kinds of effect but things an angry meeting at work or a big row with someone will produce the same phenomenon. When you take some time away from the stress, your brain will get working on whatever stressful events happened, and before you know it you'll find yourself going over that work conversation in your head again, or wondering if you'd said something different your girlfriend wouldn't have thrown her drink over you! The fact that games can encourage the same responses from the body demonstrates that they can be truly engaging and awesome!
I've had a few of those lingering effects, mainly many years ago. Here are the ones I can remember.
1) After playing Quake 1 DM as a student, getting ready to sleep and on my closed eyelids I can see Quake corridors pass by as I charged through them!
2) Lying on a beach in Greece, chilling out and sunbathing and images of exploring tombs in Morrowind wouldn't go away on the first day there!
3) Queueing at the tube for work in the morning, I was in the entrance to the station. I was thinking "just imagine if a car sped off the road and crashed down the steps here and a police car followed and crashed on top of it". Then I snapped out of it and realised that this was real life and that was very unlikely
That was when eiter GTAIII or Vice City was the big thing, I can't remember now.
