Horror, Fantasy, and Sci Fi

I live with you is (supposedly) a woman who lives in the crawl spaces of strangers (cafe's, department stores, etc.) and watches and 'changes' their lives. This woman follows You home (also could be a woman) and see that they are alike in most aspects of their lives.  I think this is very unrealistic and just unnerving and unsettling for the most part, like this person or being, just attaches to someone just like them to somewhat live through them. They never steal from the person or business they live in, just 'borrowing' or using until no longer able. Anyways this woman involves another person into this life, some random old man she saw at the grocery store and tries to get You to fall in love with him to add spice to You's life. Long story short it blows and You notices this woman and the woman decides to leave You's house that very night. This story was almost surrealist to me like this woman never felt like a person, this woman always felt like an emo

This short story has a numb tone to it. The flashbacks and descriptions of the world are very vivid and truly make me feel like I'm there, but when brought back to the current state of this world I feel almost empty and the whimsy and wonder of the past is gone. I guess that's how they wanted us to feel. I feel like Parker misses how the world used to be (i feel him on that one) and how wide technology had expanded. Now, he is left in the rubble of what once was. He doesn't hate the world? But he is definitely not satisfied with how it's turned out. Kinda like if the beautiful national parks were replaced with cheap shopping centers, it's sort of that feeling.
