It was not a frightening dream so much as a frustrating one.

Eight hours later Nicole woke up with a start from a frightening dream.

The cymeks were like monsters from his most frightening dreams.

Suddenly the child awoke from some frightening dream and began to scream.

He had had his own share of frightening dreams as a boy.

Still trembling from my frightening dream, I climbed silently out of bed.
