I have personally experienced that metadata getting messed up - one day I found myself with a very vivid memory of having recently, in real life, an anxiety attack while crossing a pedestrian suspension bridge across a river near my home. But there is no such bridge, and I could also not tell when exactly this had happened. The only explanation I have is that this was a dream that my brain somehow misfiled as a real experience. In constrast, I otherwise never remember my dreams unless I wake in the middle of one, and even then they completely fade from my memory within minutes.
