I was dreaming that I needed to wash out all of our orange dish detergent down the sink for some reason, and then I recalled a time to when I was like 10 years old and that when my mother did this, a monster appeared in the sink. Curious if I was remembering correctly, I looked up a video on my phone to see what that was all about. I learned that the dish detergent got kind of foamy and solid when in contact with water and if too much is washed down a drain then the foam could clump together and create a creature named The Bulwark Monster.
The video tried to explain some facts about the Bulwark monster, stating its urinary system is almost identical to humans and in most cases will appear very far underground but slowly rise up meaning it would take hundreds of hours for the bulwark monster to reach your home. It wasn't so large (about the size of a tissue box) but still very menacing and a pain to get rid of. I don't think the video said how to get rid of it, and the dream ended after I tried to garbage-disposal the foam and it ended up flying everywhere and I got worried it would create multiple bulwark monsters.
