The Apartment

I had a very horror dream last night.
It was about a family decided to buy one old apartment building. It almost like they spend their whole money to that building.
There was this Chinese restaurant on the front of the lobby. The old man owned the restaurant seemed very angry at the family on the day they're moving-in.
The family started to see each of room and they were all studio room size. One of the child actually really interested with the architecture and interior design so she documented most of the rooms. Oddly, she seemed had sensing people were still living inside those empty apartment rooms, like moving shadows.
On the next morning, the old man, the owner of that Chinese restaurant still opening in front of the lobby of apartment and the Father started on conversation with him but the family just stayed inside without knowing what were they talking.
The youngest child actually started to play with the shadows in the apartment. When the sister caught her, turns out she was playing alone but with old painting hanged on the wall. It looks like be left behind by the previous owner.
That late night became odd feeling for the second child as their parents start to sound so anxious. But anyway the child who loves the interior design decided to walk around the apartment in the middle of the night, and she saw it too, those shadows living on each apartment room, as if they were living ghosts.
She thought it wouldn't actually harm their family so she leave it on quietly.
Until on the next days, things pretty much changed.
Her family started to look like strangers, and somehow there were new promising tenants came by and stayed, but felt like they already lived here before.
None of them really care but the child then started to came to her Father and learned her Father actually knew. He actually becoming so confused with his own family faces. But, like the apartment feels already crowded and the restaurant also always good with the sales and like he just drowned into his own world he's seeing.
But not the child. One night she decided to stop everything because she felt they start go harm. Like, those paintings moving on her little sister and controlling her. So she brought all family to see the sister. But they thing she's delusional. It seems like the little sister had been possessed by the old grandmother spirit who lived alone on the room. The sister could see some of pictures inside her head that the old grandmother used to sleep on this old rocking chair.
It was already rotten from lower floor to the upper floor. The child screaming because her older sister started to shouted at her with pray. All family went to their room and their minds started to learn the truce. They were starting seeing what actually scary in this apartment that they all this time had been locked within themselves like somehow something enforced them to not see it. And now, the Apartment angry because the child shouted the prayers to exorcist.
The Father and the Mother started to argue if they have to leave this apartment immediately.
So, at dawn, the older sister got attacked by the spirits of the Apartment that's when the Family learned they have to save her.
But anyway they made it to save each other and started to leave the building. They still have to get their personal things. And somehow they attacked by the spirits of each room. But they made it to gathered again. Then, one final time they have to go down to the first floor from the upper floor.

When they finally arrived at the lobby, they did not look back. And people already on that Chinese restaurant. The family knew there was something going on with the restaurant like mostly the way they're calling victims and enter the Apartment. The Familly scattered them out.

No one really actually see the old Chinese man at the end.
