Again, you might fight saturation or even a standing puddle. Look at the roof above it. It is probably damaged or at least leaking. Some of the shingling might be loose. Go outside and look at the roof in roughly that spot. There probably is some sort of damage.

Unless you are an expert handyman, it is necessary to contact an expert who specializes in ceiling repair water damage, and it will likely cost you at least a few hundred dollars.
Repair to a damaged ceiling typically occurs as follows: As soon as it stops raining and the roof is dry, the damaged area must be covered with plastic to prevent further leaking. This will be the likely cause of the problem, because water piping typically runs between the walls and under the floor. The damaged part of the ceiling can be allowed to dry, but it is better if the sagging portion be cut out and replaced with ceiling-type drywall. Even though it is called drywall, it is made with gypsum, and gypsum can absorb water. The new piece will be nailed and then plastered in place.
