Morphology

arousal = arouse (transparent) = arouse + al

This sense (waking from sleep or becoming alert) is a direct and literal nominalization of 'arouse' and should be inferable from the verb.

Etymology

Arousal comes from the verb arouse (from a- + rouse), with rouse meaning 'wake' or 'stir'. So in sleep terms arousal is the process of being 'woken' or moved into alertness from rest.
