The giant Fish beneath the deep Water

"I was swimming in water way deeper than made sense, could see clear down into it somehow, and something huge passed underneath, shadow bigger than a boat, and instead of scaring me it just made my heart race good, wanted to see it again. It circled back, some kind of fish I couldn't name, colors shifting on it that don't exist on real fish, and I reached down toward it without thinking twice. it brushed right past my hand, skin smooth, cooler than the water around it. Smaller fish showed up out of nowhere, swarms of them, moving around my legs like they were choreographed, and I just kept turning trying to watch all of it at once, this buzzing excitement building the whole time. The big one surfaced once near me, huge eye looking right at me for a second, then gone, diving back down fast. stayed out there a while longer hoping it'd come back. woke up still feeling that same charged excitement, hard to shake off right away."
