So I was with my sisters inside the house where I grew up. There were these weird roots poking through the ceiling; they were moving.
I noticed these small green plants, small succulent rosettes, emerging on the carpet and the upper floor. Smaller ones on the stairs, getting bigger and more developed the further up the stairs they got.
There were two rooms at the top of the stairs, one on either side; the doors opened, and a triffid emerged from the girls' room.
