Explanation:
A adverb is a dependent clause that functions as an adverb.
This means that this part of a sentence could not stand on its own a separate sentence without the independent part of the sentence.
in my personal oppinion, sitting around a campfire in the wild or just outside of your house really sets the mood for any scary story that you might think of
This "italicized" part of the sentence is an adjectival dependent clause. It acts as an adjective to the word motorist and cannot stand alone without putting it with an independent sentence, such as "The motorist lost his way."
