Freaky dream, needs interpreting.?

OK, so it starts with me chilling with my sister, then we get kidnapped, and the whole dream we are trying to escape and find our way home. i eventually get free and go home, but then i realise i am dead and a spirit. so i go back for my sister, i help her escape, but she gets lost. i know the way home, but i can't tell her, cuz i'm dead. so i mark leaves, and she finds her way home, but then she ends up dead too... I woke up crying, my pillow was covered in tears. WHAT DOES IT MEAN?!
