I will try to reproduce this as best as possible.
I find myself plunged into a strange, water covered world, where there is an end less sea and nothing in sight. My physical form seemed to be that of a floating speck of light, twinkling like a star. I witnessed a war between what looked like humanoid species with technological advancements enough to keep them alive in this waterworld, with warships and other devices for combat, and aberrant sea creatures of all species. Massive sharks attacking ships and swallowing them whole, devouring the men aboard. Great tentacled beasts that I can't rightly describe in my memory, pre-historic looking fish with spines and all sorts of other alien creatures. I was like a spectator in this event to hold dominance of the evolution of the planet, and it definitely looked like the humanoids were losing. That was only part one of the dream.
I traveled the vast depths of the planet ocean and came across an abyssal fortress deep under the water. Odd shapes and angles, nothing remotely human about it. I traveled in still in my light body to see what it was. The walls seemed to go on forever, and were covered in very odd and intricate patterns, something reminding me of a hybrid between Giger and Lovecraftian descript. Halls in every direction, endless rooms. My journey through the place seemed to go on forever until I hit what I can only call the nucleus of the alien construct. There was a pit of tentacles in a domed room, which I traveled down into. I plunged deep within the bed of squirming mass, kept going and going until I could not stop. As I was flying through this universe of flesh, I could glimpse outlines of stars and planets, and it made me realize I was crossing over into another dimension through the portal of tentacles. I didn't stop though, and in my travel I could recall myself being taken to many strange places, seeing an assortment of equally strange things. My last memory of the dream before finding myself to be awoke in the real world was of a great pair of eyes off into the blackness of space.
