Closed A past secret for me Solo

The corridor was bustling, as usual, students running around, frantically toward their next classes, painting shouting complaint, and the occasional help with traffic, and the room seemingly though most likely responding to the madness. Extressia wasn't exactly one of those people with frantic eyes right now. She finished her work for the day, and she was close to the class with plenty of time to spare. But that didn't mean she was pushing for some space with the other people.
"I really wish the hall would magically widen so that they not practically in my face, wait maybe they ca-"
Before she could finish that thought, a bad shoulder from an unknown student push her into the wall, sending her spiraling into a wall. Extressia didn't have the chance to try to regain control of her footing and tried her best to shield herself from the wall damage. But it never came, instead, when Extressia opened her eyes, she was in a narrow tunnel with torches lighting the way. She had no idea how she got in here, while definitely nervous to get away out, there was another feeling that felt somehow familiar, a feeling that can't exactly be described but the best way to say was that like a past incarnation of her knew and went into this place.
"Oh my god, I found a secret tunnel?!" She cried out in excitement and fear
She read so many stories about someone founding a secret that start their hero journey, she kind of wondered if that what happened to her, would she save the school, even the world. It started feeding her anxiety
"Probably not." Extressia thought cutting through the emotion
"There were many secrets in a magical school like Hogwart. There are probably way more secrets in Hogwart than a tunnel." she continues thinking.
But still, Extressia wanted to know where the tunnel lead. The tunnel was dark but not too much she couldn't see. So taking one step at a time, Extressia delve into this secret tunnel.
Eventually she found the end of the tunnel, it was fill with pillows which has been gathering plenty of dust.
"Look like it been a long time anyone been here." she thought
Laying on top of the pillow, a feeling came onto her back, it was rough feeling like wood, while the rest of her body felt the fluffiness of the pillow. Turning her back she saw a book, with the title:
"Diary of Jasmine or me."
This was a diary, with a very familiar name. It was her mother's name.
