Invincible but imprisoned - death over and over again

Date: 4/29/2019

I dreamt that I was driven out with all my friends to the Swiss Alps or something. We were locked up and I hated it and wanted to escape. I’ve were brought outside and had to swim in a lake and tread water in a circle. A woman who felt familiar asked me to help as a volunteer. I asked her what for but she ignored me and brought me over to a wooden machine. Before I could protest she cut my head off. I woke up inside the small hut in the bathtub, alive. I knew I had just died a second ago. I walked out to the lake and saw everyone looking shocked at seeing me just die. The woman pointed at me and demonstrated how we were all invincible and they needed to study our death patterns. I scratched my neck. She made everyone gather into the bathtub (there was like 30 of us but we shrunk to fit) and set a countdown. We had to die as quickly as possible. The countdown ran out and so we all went out into the snow. I took my time and wanted to escape. My friend found a car and asked me to escape with her. I knew we wouldn’t make it and begged her not to go. She went anyway. I don’t think she made it. I just kept dying and waking up in the cold bathtub.
