This happened to me about three years ago on the A35 coming back through Dorset late at night. Left a friends house at 11pm, should have been home by midnight, got in at gone 2am with absolutely no memory of the extra time. No traffic, no stops, nothing. I pulled over in a bit of a state and just sat there trying to piece it together.
The weird part was my car had more mileage than it should have done for that route. I've driven it hundreds of times. I know exactly what the mileage should look like.
Did you feel strange afterwards? I had this really heavy feeling in my head for a few days and kept waking up at 3am. Never got a proper explanation for it and honestly I stopped trying after a while because it scared me too much to dig into it.
Would be good to hear if others experienced physical symptoms after or if it was just the time gap itself.
