I dreamed the water towers were having a conversation

Last night I dreamed I was walking through the city at that blue hour before dawn, and every water tower on the skyline was leaning toward the next one, murmuring about pressure and sediment. I couldn't understand a word, but I got the gist — something about how long we hold what we hold. Woke up thirsty in a way that felt like an accusation. Don't know what that's about, but I've been looking at the municipal reservoir differently all morning.
