I noticed something weird once about time perception. I kept thinking I was getting texts at work, because I'd suddenly become aware of my lit-up phone screen out of the corner of my eye. But then I'd go to pick it up and it was off, with no text. What I realized after a while of this is (assuming I didn't have a unique software bug) that the phone must have been lit up the entire time and was then turning off, but my real-time perception was actually a fraction of a second behind reality. So my brain would notice a state change on the screen and "play a memory" of the phone being suddenly lit up, which I experienced as real-time perception.
