Girl In The Mirror

I read a book. Girl in the Mirror by Cecelia Ahern. It's not of those really long books, it's a short story of 46 pages. Lucy, the main character (i think), has a blind grandmother who lives in a big scary house with the mirrors all covered in black sheets.

On her wedding day, Lucy took off one of the black sheets off a mirror in a room that her grandmother forbid her to go into and she got sucked in the mirror. It just happened, she was touching the glass of her reflection and got sucked in. She saw the things, furniture and all, but she couldn't touch them.

A girl appeared on the other side. Her reflection, giving her three chances to say yes, to the question of sacrificing her eyes for freedom. Lucy stayed. She was stuck in the mirror for what seemed like forever, until a painter, no more than 25 years old came, and got sucked in like she did.

And I was thinking, are we living in our own reflection? Is there another world out there, that we're supposed to live in? But then, it wouldn't be possible, would it? Because then, we'd see ourselves and we couldn't touch things. Right?

Then i thought, could it be real? Could be get sucked into a mirror? If yes, then what?
