yeah you were probably just seeing things. I could relate though. When I was a kid, when I first encountered the RSOD on my old PS2, I thought something possessed my PS2. But no, it was just an error. There was also this weird glitch in my copy of Twilight Princess a long time ago, the first part of the battle music didn’t play and it was just silence, until I moved closer to the enemy where the backing track played by itself. The glitch never occurred again, it was the result of a dying disc laser.
