Salt Water and Murder?

Date: 2/5/2017

So this dream really messed me up because it isn't the first time I've had a dream about being a killer. It freaks me out because Im not even capable of killing a spider. Anyway I was with people (I can't remember their faces) and we had hostages? Enemies? There was a large container full of salt water (industrial size) was there and we had these people hanging above it upside down. Someone told me that salt water is one of the best ways to kill someone. So we dunked them into the container and drowned them. However later we were after someone else but somehow the container was now filled with coco pops and milk so people came and played on it. Confusing to say the least. P.S. I actually googled how a person drowns from salt water and it came up telling me the salt water draws blood from your bloodstream and into your air sacks - blocking oxygen. You essentially drown in your own fluid.
