Both. Rebekah's brother sacrificed me to undo some curse on him, and my biological father used a magic spell so that...his life force would flow into me when I died. Or something. Because he didn't want me to become a vampire.
I felt like... When I woke up, it was like I was out of breath and that I had lost time. My body felt all tingly (not in a good way) and breathing kinda hurt for a minute.
