I am trying to write without description, only narrating the perceptions of my protagonist, both external (what happens) and internal (what she thinks). I want to avoid all those explanations that are obviously only added for the benefit of the reader but wouldn't be part of the protagonist's actual experience.
Sometimes I feel as if my characters and events are "floating in space"; as if they are appearing unrelated and meaningless to a reader, who has yet to read far enough to understand the underlying plot.
I am uncertain whether or not I should add in some description to connect the "free-floating" bits.
Here is an example from my own writing to illustrate what I'm talking about. The original, without description:
So how did this animal suicide thing start? Ironically, it began the night I decided to die. But why? I had good health, friends and family who cared about me, plus I'd just been admitted into university.
The only thing we know is that it's nighttime and the main character is in her apartment, searching stuff on the Internet.
I felt this was not enough to provide context and meaning for the reader, so I added some description:
So how did this animal suicide thing start? Ironically, it began the night I decided to die. That's right: I locked myself in my apartment, closed the blinds, and, veiled in the darkness, planned how to end with my life. But why? I had good health, friends and family who cared about me, plus I'd just been admitted into university.
Is doing this justifiable? Did I improve the passage with the extra description or just added unnecessary clutter?
