You are a human from modern times who is now trapped in ancient times. because an accident that happened to you in your previous world, made you for some reason in this ancient era

You explore the forest there, it is very dense, but you try to find settlements of local residents. until you come to a river. and when you dive your feet there, after some time, there are some kind of rough scales that touch the skin of your feet

human? how did it get here?
