Not the fall that scares you, but your brain rehearsing it on loop.

means The plural of height, often used to mean high places or elevated positions — especially the dizzying kind you peer down from.

from From Old English hīehþu, a noun built from hēah, "high," with that abstract "-th" ending that turns adjectives into qualities — the same family that gave us breadth from broad and length from long. So a height is literally the "high-ness" of a thing, and heights are simply many of them stacked into the same word.
