I Dreamed of a Celestial Descent into a Galactic Abyss

so basically, the dream starts here. It starts off with me on a really wide branch, and the room I am in is MASSIVE, and it looks like it kept going down forever. And the branches, they were spread out everywhere, they were horizontal reaching from wall to wall. And they seemed super, celestial, ethereal, mythical type of thing, like in the picture, and the sound of the dream, it was super kinda relaxing, kinda like water flowing. And from what I can remember, I was making my way down the branches carefully, until I reached the bottom. I don’t have much memory of the journey to the bottom but, whenever I reached the bottom, it was almost pitch black, I was in a endless abyss of water, and the water, had a galaxy like reflection reflecting off of it (btw the water wasn’t really deep I was kinda sitting in it) and at the end of the dream, i think i saw a outline of a girl, and she also had a galactic type pattern to her reflecting off of her. I heard the water splashing when she was walking towards me, and that’s where it ended, whenever I saw “her” I wasn’t scared at all, more curious and a feeling of me being “safe”. Her presence/essence was, really strong. That’s where it ended.
