He ran like a creature pursued by unseen demons.

All that Jasper said she had heard whispered about her by unseen demons who had tortured her for days with these horrible suspicions.

There were no unseen demons hovering overhead.

The vermin ran as if chased by unseen demons, each trying not to be at the back of the horde, which was the most vulnerable position.

One minute, she is an overgrown infant, quaking and crying, pursued to the brink of suicide by unseen demons.

But no unseen demon reached out for him; no writhing shadow lurked beyond the nimbus of light.

They bounded against him like a monstrous hail, like missiles flung by unseen demons.

This was something akin to the unseen demon that had come to the place where they had drawn Jake.

From within there were flickerings of some ungodly light, like unseen demons dancing around a towering pyre.
