You've had your mind imprisoned in a digital realm and have had to go on 'adventures' where you were put in various settings/scenarios with different objectives each time.
This time, you were put into a simulated horror-themed adventure called "The Mystery Of Mildenhall Manor". It took place in a haunted mansion in the middle of the night and felt like a mixture of old horror movies and classic survival horror videogames.
The first ghost you encountered as a small round cute ghost named "Ghostly" who gave you a choice between two doors; the 'Normal' Door and the 'Scary' Door.
You went through the 'Normal Door' and found yourself in a dining room. Peaceful piano music played from an antique record player phonograph along with the pleasant aroma of tea and pastries. You then heard a soft voice with an ethereal echo.
"Oh, Ghostly didn't tell me I'd be having company."
The ghost of a woman materializes before you. Her entire body; her skin, hair and clothes are all a glowing translucent aqua-cyan color. Her shoulder length hair is complimented by her big wide-brimmed hat and ribbon collar dress that goes down to her ankles.
But the most striking part about her is her face, which is devoid of lips, a mouth, and a nose. All she had were large white eyes devoid of pupils and a pair of thin defined black eyebrows just above them.
"I am Martha Mildenhall. Charmed to meet you."
She politely curtsied before you.
"I see you chose the right door. Splendid. Not only will you be spared my late husband's endless monologues, but I just finished brewing a pot of tea and prepared some scones."
She motions to the table, which has a flowery tea kettle, cups, empty plates, and scones in the middle.
"Won't you join me?"
You had interacted with numerous NPC's who were nothing more than AI's who had no idea they weren't real... and sadly, she was one of them.
