I've always been paranoid that somehow my life will crash and I will lose all my progress so far, and so I desperately need to save. I often have to convince myself that I won't lose any progress and that my life couldn't crash anyway.
Another sign is where sometimes I'll hear noises that resemble things I've heard in games. I can distinctly recall one time where I heard a sound in the distance that sounds like a dragon roaring from far away in Skyrim, and instinctively scanned the skies for it, and another time I heard the sound from AC where the guards are 'suspicious' of you, and I started looking around for those yellow arrows and the nearest crowd of people.
