My younger sister hasn't seen her dad her whole life, shes nearly 6 and in these years i have had so much hatred for the guy. some people tell me its because i have a lot of questions to ask him as i have no answers what happens in this dream is unthinkable but every time i have it i wake up swinging my arm as if I'm punching someone. This is becoming an issue as its happened twice round my friends house and me and her sleep quite close. Does this 'nightmare' have a meaning to it?
