Sunlight streamed through the newly installed kitchen window, illuminating dust motes dancing in the air. Sarah hummed, the sound bouncing off the freshly painted walls. This house, finally *hers*, felt like a dream come true. She tugged at the handle of the old pantry door, expecting resistance, but it swung inward with surprising ease, revealing not a cluttered storage space, but a narrow, dark hallway. Her lips curved upwards in an instant grin.

Taking a tentative step inside, she reached for a light switch. There wasn’t one. “Well, this is an adventure!” she chirped to the empty space, her voice echoing slightly. Grabbing her phone, she activated the flashlight. The beam danced across a peeling wallpaper, revealing a small wooden door at the end of the hall.

Her heart did a little skip as she approached it. This was going to be fun.
