I once had this vivid nightmare, where one morning the whole world's drinking water is suddenly infested with parasitic white worms, like maggots, except tinier.
I still lived in my grandma's house back then, so this took place there.
I woke up (in the dream, yeah), with an insane thirst, but when I went into the kitchen, I saw everyone drinking water already.
Suddenly, all of them start having these strange seizures, and I remember ceramic mugs crashing onto my grandma's pink kitchen tiles, water spilling everywhere. And then, out of the spilt water, worms were crawling in every direction.
Freaking out, I backed away from the kitchen, and then my own mother stopped shaking violently, and came towards me, all pale-like, telling me to have a cup of water, saying its healthy and good.
Yeah, as if I would drink a cup full of maggots.
So I ran, to my grandpa's large garden, through the entrance, and accidentally entered the bathroom.
It was kinda traumatizing to see your own uncle, sitting in a bath tub full of water crawling with the same worms you just saw crawling out of the very same mugs on the kitchen floor.
He started getting out of the tub, and I remember a lot of screaming (from me) and then I ran into my room, and barricaded it.... and they pounded on my room door, almost breaking it off the hinges...
And then I woke up crying.
