Dream About Girl Traveling Rivers Canoe Jellyfish Like Creatures

This dream was about

Weird dream I had that was in the style of studio Ghibli! Was about a girl who was traveling the rivers by canoe. Strange jellyfish like creatures followed her. They were clear, flat and blended in to the water. They were friendly and caused the girl no harm. Sense they were hard to see she either placed something on them or drew on them to make them appear to have eyes. so she could more easy see them. Another creature followed that was more like a friend to her. it could transform from being solid or a creature of water. When a creature of water it almost appeared like a Maroge in the water. For if an object got in its way or was thrown at it it would disperse like water does, then reform back together. At the end of her path the river became small and shallow almost like a creek. At the end, bellow the water is what appeared to be a small castle that all of the creatures of water went into. I think the creature that was her friend somehow shrunk her so she too could enter the small castle with the rest of the water creatures. Then I think the dream ended.
