Getting random flashes about tv shows/movies i end up seeing later...

This happens a lot, as in most every day. Just this morning I woke up and randomly thought about a particular scene from a tv show I've been watching a lot; then again when I was brushing my teeth; then when I was just getting some stuff from my nightstand. A different scene every time. And now there's a marathon on tv and I'm here, going: "Oh, I randomly thought about this scene when I was grocery shopping" etc...

It's like I have the dialogue memorized; it just randomly replays in my head for seemingly no reason at all. Later, usually the same day, it somehow becomes a part of my day. Like when a tv show is on and the exact episode I've thought of is on.

Sometimes I just "forget" about getting a flash like that until I actually see it on tv and then remember I've already "seen" it.

Occasionally I can make use of this; when I'm wondering what to do with my freetime I riffle through my movie/video game collection and upon looking at something realize some part of this tv show show/movie/game I own has been on my mind today.

In situations like this I always, ALWAYS choose things that have popped to my mind like that. It hasn't ever ended badly so I don't see a reason to change my course of action.

So what I'm asking is, are these kinds of flashes normal...?

(On a side note; this does only seem to happen with tv shows, movies and games I'm familiar with. Not with real life people or happenings so I'm not really sure what to call this...)
