In the darkness, flames could be seen flashing inside the controls.

But somebody seems to be flashing a light from just inside the door.

Shots of red, blue and yellow flashed inside my head.

Flashing red lights inside a large room caught my eye.

The man went to the door and flashed his torch inside the dungeon.

The room flashed with a kind of invisible light inside their heads.

Think of that thing flashing its digits inside a coffin during the day.

At none of them did anyone do more than flash a light inside the truck.

Flash his light inside to see what was there?

That insight made light bulbs flash inside every head in the office.
