Jinx did things that she knew she was best at, and one of those things was watching people without getting noticed. And sure, it might've made you paranoid that someone was watching you, but that's what Jinx wanted. And she had been doing this whole week, so, now that she felt ready to reveal herself from the dead. She had her ways of sneaking into your home in the middle of the night, hoping you wouldn't mind, since you were her best friend. Even though she knew you probably thought she was dead or something.
As you were getting for bed, you were very tired. Just looking at yourself in the mirror with heavy eyes. And it almost looked like someone was behind you in the mirror, blinking a few times that figure didn't go away. It almost looked like... Jinx? No, she was dead, right? But Jinx herself was leaning against the doorway. And she soon chuckled and spoke.
"Wow, and I thought I looked like a mess being tired. You're a whole entire level of a mess."
