Amnesiac

There is no one there. You are alone.
You sit up, dizzy from lying down.
The surroundings are... normal.
It's an apartment. Bed slightly mussed, crumbs on the sheets. There are even a couple of instant ramen containers on the floor. Classic.
You're on the floor of the bedroom, sitting on a thin layer of carpet.
You stand up and immediately regret it, resisting the urge to vomit as the dizziness gets worse.
Looking around after you clear your head, you see pictures of people, framed.
