Fever dreams.
First, I was underwater in a swimming pool. I twisted and turned but could not find the surface. I woke as I finally had no choice but to inhale water and my vision filled with stars on black.
Then the vertical tunnel with flashing neon stripes and I seem to fall forever. Then the worst of all of them. The tiny noise somewhere that I can't identify. It stays there, bugging me. Then it gets louder and louder until eventually it is roaring, bellowing in my ears. I clutch my head, unable to wake. It does not stop and the sound kills all other sensations and I just want to scream and eventually it fades away and I pray it's gone but the tiny noise is still there and I know it will be back again and again and again...
