Right so I wasn't on Route 9 but this is reminding me of something that happened on the A6 near Matlock about four years back. Left a mate's house at half ten, pulled onto my drive and it was gone two in the morning. I know that road like the back of my hand, I've driven it probably a thousand times. There's no version of events where it takes three and a half hours.
What I remember is a light sitting very low over the reservoir - not moving, just sitting there - and then basically nothing until I was indicating to turn onto my street.
The thing that doesn't get talked about enough with these cases is the aftermath. The week following I was exhausted in a way I can't really describe, kept waking up at 3am exactly, and had a nosebleed every morning for about five days. That last bit still bothers me more than the missing time honestly.
Anyone on this thread who experienced something similar last Thursday - please do write it all down before the details start fading, because they will.
