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 the apparently haunted house, believing the ghost was her dead sister's soul 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.
