Her Instagram following jumped from 651 to 100,000 overnight. Sarah stared at her phone, puzzled. Every new follower's profile picture showed the same thing: her sleeping face, photographed from above her bed.
Each account had posted a single photo – different angles of her bedroom, all timestamped from last night. In some, a dark figure stood in the corner, growing clearer with each post.
She scrolled frantically. The figure moved closer to her bed in each subsequent photo.
Her phone pinged: "Going viral! 250,000 followers!"
The latest photos showed the figure leaning over her sleeping form, its face a blur of static.
Another ping: "500,000 followers!"
Sarah looked up at her bedroom ceiling. The hidden camera she'd installed last week blinked steadily. But she hadn't installed it.
Her phone buzzed one final time: "Live stream starting in 3...2...1..."
The lights went out. In the darkness, thousands of tiny red recording lights blinked from every corner of her room.
