The eclipses in these lines give us a scattered, stream of consciousness vibe, which completely serves that Lou is described as “pure primal id.” From the get-go, we’re almost in his head. 

Likewise, note that before we see the character in person, we see his silhouette or shadow. Oftentimes in literature, the id part of the psyche is represented by shadows or the archetype of “the shadow.” 

It’s not coincidental that the first thing we see Lou doing is something illicit. All of these things “id” elements are unified and interconnected.
