hi i am really worried about my little brother, he is 6 years old and is 7 on march 20th and he has been waking up in the last two weeks really scared, he has done it twice so far, and it is a nightmare he is having. But when he wakes up from it he is all worried about everything, it has just happened then he woke up and wanted to get out of the house and kept pointing at the tree and crying then he started to point at the radiator and cry, but he was scared of his mum and kept saying he didnt want to die and he was scared..why is he doing this ? has he seen something that has scared him ?
