wish I could’ve stopped it

Date: 8/7/2019

It started with me & my sister, the one I haven’t seen in a long time, and we were at the beach. we were holding hands and walking alongside the ocean. it was sunset and it escalated pretty quickly into night time. the stars were visible and she pointed at them. we sat down on the sand and looked at the sky for a while. until I was put into a different perspective, it was another me and I was watching me & my sis both get up. I wanted to follow them so I did but some invisible barrier kept me from going further. I started panicking after I saw the other me push my sister into the water. She fell and was trying to get up but I was watching the other me push her back, this time forcing her head under the water. and it gets too graphic from there I basically watched myself drown my sister I woke up in a cold sweat
