Lost time.
My brother was helping me across the country. We borrowed a van and loaded everything up for the last trip. Just before we left I checked my watch and called my gf that we would be hitting the road soon. My brothee checked the kitchen clock but only told me later he did.
We set out but couldn't do more than 80 km/h because of the load. When we took the offramp of my new city my brother told me he couldn't remember the trip, when I thought about it, neither could I. We both thought we where tired and thought nothing of it. However when we arrived at my new house my gf asked if I broke the speedlimit because we where almost an hour early. When retracing the route, my brother and I both agreed that we can remember passing a certain gasstation and nothing thereafter, until the offramp.
To this day we have no clue what happened during that hour we're missing or how we could have traveled that fast. Not with any car or van atleast.
Now at the beginning I wrote we both independently checked for time, this is important for us because one time source could have been wrong but not both. Also I called before we left which limits the time we could use to travel.
Since then we have never experienced any weirdness like it or otherwise. I don't have any weird memories or dreams, no piece(s) of metal lodged under my skin, etc. Just an hour I lost.
