Many years ago, the author went to a forest sleepover to celebrate her mother's birthday. At night, she heard strange noises and saw a ghostly figure of a child at the window. Though scared, she didn't want to ruin the birthday celebration. After a few days of nightmares, she left, believing the figure was the soul of her dead sister wanting to be near their mother on her special day. Now, she sometimes hears a voice but feels it's her sister's, so she's not alone.
