We do get a quick heads up, but ya I would die too probably because that was a vastly different world than what we have today. Especially since we basically own nothing now because it’s 1000 years in the past. I mean, if there’s someone skilled enough, they can just try to take some useful stuff they’re skilled at for survival while they get transported to the past.

Another reason being taken back a thousand years can be terrible is because English was really different back then. If you need help, no one will understand you plus they’ll probably be a little hostile because they don’t understand you.
