Into Squid City (did I use Emily already for this?!)

"Why do you always shut me out?!" Jacob shouted.
Emily leaned her back against the door, feeling it shake beneath his pounding fists. He did not mean it literally of course but she did that too, when his words became too painful and she couldn't stand to see his scowling face a minute longer. In a way it would have been easier if the physical side of it was all there was but of course the pain was emotional too. She shut him out of her heart because he wreaked too much havoc there.
"Emily, open the door!"
"Leave me alone, Jacob!" She shouted back, slamming the lock across and retreating across the room. He continued to shout and she covered her ears with her hands, wishing he would just go away.
"This is my house too!" He continued. "You can't do this!"
The more he hammered on the door the more afraid she got. Jacob's voice echoed in her mind until she felt like she was going to go insane - and when she heard wood splintering she almost screamed.
When Emily had been little and her father was drunk and angry, her mother had taught her to hide. Those instincts kicked in now and without thinking she crawled underneath the bed. The dusty darkness smelled like her childhood and remembered terror overwhelmed her. Crying silently Emily shuffled in further until her face was pressed up against the wall.
"I'm going to break this fucking door down!" Her father shouted with Jacob's voice. The wood creaked and Emily scrabbled blindly at the wood as if she could open a hole in it and escape.
And then, just as the door gave and Jacob stormed into the room, the wall opened like a door before her and, without hesitating for a second, she crawled through.
She could hear Jacob raging as he tore the room apart but she had kicked the wall closed behind her and the darkness that closed in around her eyes seemed to muffle the sound too. After a few seconds she couldn't hear a thing except her own panting breath and the scrape of her limbs against whatever she was crawling along - and then the darkness began to ease, and there was a glow of light from ahead of her. She knew she hadn't headed downwards so that meant she was about to come face to face with clear air several stories above the street. There was nowhere to go.
With a howl of despair she threw herself forward again, because if he was going to come after her then she'd be damned if she was going to let him catch her. Then, without warning, the light was not in front of her but underneath her sweaty palms and the vent gave way. Her heart flew up into her mouth as she fell and then before she could scream she had landed on soft green grass, and above her the sky was a crisp blue chased with threads of cloud.
Bewildered Emily struggled to her feet, leaning against the tree that she had, impossibly, fallen out of. It was big and ancient-looking, and almost every inch of it was covered with door and windows and hatches of every imaginable kind. For a momen Emily thought that she must be dead, but death couldn't hurt as much as she did now - she was a bruise from head to foot. There was only one alternative.
"I've snapped," Emily whispered, brushing dust and grass from her clothing. "I've gone insane."
Tiny daisies nodded in the sunshine and, at the bottom of a short slope, the ocean gently lapped against the tree's little island. The water was clearer than any she'd ever seen, and beyond it a shining stone city rose up like some kind of miracle. When she compared this bright and warm place to the cold, gray world she had left behind Emily knew that it couldn't be true.
With a smile she sat down and then lay back, letting the sunshine dry the tears from her cheeks. She knew it couldn't be true, but she also knew she didn't want to leave.
