I had this when I played Minecraft a lot. My wife and I (who both played for hours on end almost daily, running servers together) both started the see the world as blocks. It changed our perception quite a bit. It didn't bother us, we thought it was cool. It didn't interfere with anything. We maintained our understanding of reality vs game. Until a creeper blew up our house IRL. That was unusual.
