Night

My first thoughts...
The narrator didn't wash the hair thoroughly... Lol
it has to do with the "pillow's bleeding shampooed liquid" and the drenched hair..

But overall, I have no clue what to think.

I guess, it's just the night. Someone showered, the hair is still wet as this someone rests in pillow. I wonder why the mentioned of bruised sky... With the pillow, I would assume this someone is in her room? Unless she is looking at the sky via the window. I think this piece works great at creating a picture with few words.
