Dream 20/10

I dreamt I was at a water park/river of some sort. I got in and started going downstream, until I realised how huge and rapid it was getting. It freaked me out so much, I thought I must've chosen the wrong day - the river must be flooding over from the rain or something - so I desperately made my way back upstream. I'm pretty sure Maya and Alaster were there somewhere. The edges of the river/pool were concrete and had stairs along the bottom in some places. It kind of had sewage/canal vibes. The water was greyish and murky and cold.
