My sad and disturbing dreams pt. 1

This is so random but I will never forget the like worst dream I ever had it was so weird!!! It's kinda long but everytime i think about it i get a little teary-eyed...

It was a long time ago so I cant rlly remember everything but basically I was walking around this bigass lake and the water was so reflective that it almost just looked like a big mirror and I walked right to the edge and just crouched down next to it. I was looking into my reflection for a little bit before something came up from the water and grabbed the sides of my head and pulled me down. 

Its hard to explain but when I got pulled into the water I died and the lower i sank into the water the more into the "underworld" I fell into. Everything got darker and darker and I had no idea that I had died or anything I was just watching as i was pulled down. Eventually it was so dark that my eyes started to hurt so i closed my eyes and when I opened them again I was in this space. It wasnt a room or anything it was just a grey space and I was just floating there.

 Suddenly a few other random people showed up and they were all scared and confused too and then this entity showed up and basically told us that we were dead and everyone was so scared it was weird and then all the dead people's chest kind of started to give off different colors and we were all a different color of the rainbow. it was so weird but a bunch of coffins showed up in front of each of us (we were in a line shoulder to shoulder) and one by one we watched the coffins open and our dead bodies were in there and every time each person saw their body they would cry and slowly fade away.

 I think i was purple so I was last, and when I started to fade away I faded back into the same grey space, but in the middle of the space was my dinning room table, and all of my favorite things were just so cluttered onto the table. I stood and watched as my sister walked up to the table and just sobbed for what seemed like forever. I couldnt do anything but watch, I wanted to scream and hug her but I couldnt move or cry or anything I was just stuck there as I watched my sister cry.

and then I woke up.
