Her heart skipped a beat, then hammered against her ribs. She was browsing online, a casual act, when the familiar red-brick facade jumped out at her. The house. Her childhood house. For sale. A wave of nausea washed over her.

She felt a strange sense of unreality. The perfectly manicured lawn, the freshly painted trim – it all looked so alien, so… new. Her mouth fell open; she couldn't seem to close it. She felt a profound sense of loss, a bottomless pit opening inside her.

She slowly leaned back in her chair, staring at the screen. She felt as though she’d been abruptly disconnected from a life that once felt so real.
