The Scream

Sitting on the bus, you overhear this conversation behind you. "Something weird happened to my neighbor last month. For about two weeks, she started having these hallucinations, seeing things, you know? And hearing things. And she kept thinking aliens had abducted her and she wasn't kidding. I couldn't convince her things were normal. She kept going on and on about things that weren't related and kept rambling too. She wasn't showering, wasn't wearing normal clothes, it was just so weird. I heard they brought her into the emergency department but everything in her body checked out okay, it was just her mind going crazy. I heard the drug screen was negative too. But then two weeks later, she was back to normal, back to her job, like nothing was wrong. It was just so weird. I guess she was pretty stressed when this all happened since she just moved here."
