SPOOKY Gemini AI Editing Prompts: Celebrate Halloween with Google Gemini Nano Banana

Prompt 1:

"A scene split by a mirror, showing a woman applying lipstick while looking at her reflection. On the left, in the reflection, the woman has long dark hair, a serious expression, and is wearing a dark top, holding a dark cup in her left hand. Two posters are visible on the green tiled wall to her left: one with a monstrous face and text, and another with a silhouette against a yellow field. In the foreground, on the right, we see the back of the woman's head as she applies red lipstick. Reflected in the mirror next to her, a menacing Chucky doll with red hair and overalls is prominently visible, staring out, creating a disturbing contrast to the woman's routine. The background is a grimy, dark green tiled bathroom. Don't change the face, make sure the face is the same."

Prompt 2:

"Create a photorealistic cinematic portrait of a woman with the exact same face as the uploaded image, sitting in a dimly lit movie theater surrounded by classic horror characters, including masked slashers, a creepy doll, and a sinister clown. They are all watching a film, holding popcorn and soda. The mood should combine horror and humor, creating a darkly comic movie scene with a touch of eerie suspense and playful irony."

Prompt 3

Make a very realistic Halloween-themed day scene of a real park, with real autumn leaves and a few unlit pumpkins on the ground. There is a bench in the middle where a woman is sitting in casual attire, and next to her is a full-sized skeleton. Focus more on the woman with the skeleton.

Prompt 4

Make a portrait of me lying on the bed, talking on a ’90s corded landline. The bedroom behind me is decorated with ’90s posters. My makeup is minimal but glamorous. A single bedside lamp lights the room. In the doorway of a dark hallway, a translucent bedsheet ghost looms, staring directly at me.

Prompt 5:

"A young woman with long dark hair is seated at an ornate wooden vanity, looking over her right shoulder directly at the viewer with a startled or worried expression. She is wearing a simple, flowing white nightgown. Her reflection in the oval mirror shows her looking forward with a similar expression, softly illuminated. In the background, above the reflection, ghostly, shadowy hands are reaching out on the wall, adding a strong, eerie, and unsettling atmosphere. To the right, a table lamp with a warm glow illuminates the scene, casting soft light and shadows. Don't change the face, make sure the face is the same."
