My little brother,he's 6,cannot sleep properly.I don't mean that he can't close his eyes and sleep but when he sleeps he wakes up very often crying-more like screaming actually-and he says things like"Leave me alone!","Go away!" and "Don't touch me!".Don't say that we treat him badly cause it's actually the opposite,my parents have always treated him so nice that i find him very spoilt.Of course the thing is that he loves playing with Transformers and Power Rangers.I know this influences him in a bad way but he won't stop playing with them.I've told my mother to take him to a phsycologist but she doesn't listen.What can this thing be?
