Do you experience derealization after reading, watching stuff, and/or playing games?

When I read books, specifically, fiction books and I stop and look up from my book it puts me into a pretty bad derealization episode. Which really sucks because I enjoy reading fiction. Same thing happens when I watch TV or play video games. I was wondering if anyone else experiences this and also if anyone has any tips on how to make the episodes not happen or be not as bad.
