What is the monster's backgroud?

The creature has only the most vague memory of his early life: he recalls being assailed with sensory impressions, and was for a long time unable to distinguish among light, sound, and smell. He began to wander, but found the heat and sunlight of the countryside oppressive; he eventually took refuge in the forest near Ingolstadt, which offered him shade. The creature found himself tormented by hunger, thirst, and bodily pain. Only the light of the moon consoled him, and he grew to love the sound of birdsong. When he attempted to imitate it, however, he found the sound of his own voice terrifying, and fell silent again. With the same ecstatic astonishment that primitive man must have felt, the creature discovers fire.

All of the people that the creature encounters in his travels regard him with horror: he is often pelted with stones and beaten with sticks.
