Mina (but not in her body so not Mina?)

I didn't remember much about how I died. I just remember being in a car then suddenly I was in someone else's body. I was laying in an open patch of grass with a huge tree above me. There was a boy laying next to me who seemed familiar and I felt like I should know him. He appeared to be asleep so I got up slowly and looked around for a mirror. I finally spotted one and saw someone else looking back at me. This person was dressed in all green and pink with green hair and black roots. Their eyes were two different colors and they had a small tattoo of two intertwining on the back of their neck. Everything about this seemed vaguely familiar.

"Hey Alex." A voice said behind me

I turned and saw the boy had gotten up. I noticed a runestone around his neck shaped similar to an F. That's when it hit me. He was Magnus Chase son of Frey. That meant I was Alex Fierro, child of Loki.

"Alex dude you ok? You look like you just saw a ghost."

"M-Magnus."

"Hey, it's ok I'm right here."

He ran forward to catch me as I swayed back and forth. I fell into his arms but didn't pass out. It was a shock. I personally didn't care for the Magnus Chase series but my friends had told me everything about it. Magnus lowered me gently to the ground. We must've been in either mine or his room at Valhalla since I've been told they look a lot alike. I laughed slightly as I realized I had died then been reincarnated as another dead person. I started laughing uncontrollably as Magnus stared down at me with concern. There was a knock at the door and Magnus headed over to answer it.

"I've brought you a new person to floor 19. I'd like you to show them around." Someone said

I looked up and saw the person talking was Sam who was also Alex's half-sister. Then I saw the newcomer. That's when I really did faint.
