My step son on Saturday night came into our room and woke my partner by stroking his arm. Because he was in such a deep sleep he literally screamed when he woke up which then prompted me to wake up screaming as well thinking that he was being murdered, all the while, his poor 7 year old was standing there wondering what the hell was going on. Ever since, I've had a horrible restless feeling in my chest and can't relax. Has this ever happened to anyone else?
