The phenomenon that influenced Victor when he was younger was the moment when he witnessed a tree being struck by lightning. This part of the story serves as a foreshadow of how Victor's creation will come to life.
Explanation:
Foreshadowing is a literary technique where the author advances information that will be seen later in the story. This information is given in a non-literal, subliminal way, to make the reader curious and anxious about how the story will unfold with the influence of this information that was advanced.
An example of this can be seen in Frankenstein, when Victor witnesses a natural phenomenon that influences how Victor will bring his creature to life. In the book, when Victor was a child, he was able to witness the moment when lightning strikes a tree. At that moment Victor witnesses the great power that a ray has. This moment is an example of foreshadowing, as Victor remembers that moment and decides to use a lightning bolt to give life to his monster.
