Huh what happened? Where am I? What is this place?

I was confused, I was dead, so how did I come back to life? I noticed the river near me, but the problem was that it wasn't me, was I in someone else's body or can wizards even do that? "Alex what the hell are you doing there come back here you useless brat!" I turned around and the first thing I noticed was the tattoos all over his body and the sword on his waist he was apparently a swordsman he shouted again "I'm talking to you you stupid brat do you want to make me repeat myself!" I was surprised I think my name was Alex I calmly replied "Are you talking to me?" when I looked at his face all I could see was a rabid dog he approached me and kicked me hard I was stunned being in a child's body made me defenseless he shouted again "Does it look like there's someone else here besides you quickly pick up your stuff you ass-legged brat!" I had to pick up the sword and similar items on the ground but my nerves were getting the best of me I would have separated his head from his body if I could but I waited
