Immediately the ceiling turned to slime and began to drool down toward the floor.

The cast-iron ceiling of her world began to shift, lift ever so slightly.

For about 10 seconds, nothing happened, but then the ceiling of the room began to glow.

But as he walked, the ceiling and floor began to converge.

The ceiling, which previously had seemed featureless, began to glow.

From one moment to the next the ceiling began to glow, to melt and to evaporate.

The ceiling began to spin as the whirlpool caught them.

Then there was a cracking noise, and the ceiling above them began to tremble.

The ceiling rose and then began to diminish above them like some weird rocket.

The ceiling began to break apart under the strain.
