What metaphors are used in Requiem for a Dream: A Novel by Hubert Selby?

Metaphor:

"The sun was down which made it night time, but Harry and Tyrone were bugged with all the lights that stabbed and slashed and skewered their eyeballs...Daytime is a drag...you look forward to the night when you can get some relief from the assaults of the day and start to come alive."
