Sometimes, when I've played a video game for long periods of time, I'll find elements of the game incorporated into my dreams. For instance, after long sessions of Minecraft, lots of my dreams have blocks in them, but it's not specifically about Minecraft.
The only time I've ever had a dream about a game was when I first played Dino Crisis 2. There was this part in a medical facility where you find a corpse on an operating table. Upon inspecting the corpse, you're told it's obvious the man was killed in his sleep. I had a dream about walking into that room, finding the corpse, and watching as it reanimates and sits up on the table.
