Without more information, it's impossible to say who Lauren is. She could be an ordinary girl, a character in a made - up story, or someone known within a particular group.
I'm not sure specifically which 'girl in closet Lauren story' you're referring to. It could be a personal anecdote, a fictional story, or something specific within a certain community or family. There's not enough information to give a detailed account.
Most likely not. 'Girl in the Closet' is probably a work of fiction. Stories like this are often made up to engage and captivate the audience rather than being based on true happenings.
