Sleepy

For almost five years now, my littlest one has had nightly nightmares.   She screams, cries, commands, or speaks entire sentences while asleep.   I have lost all hope that this is just a phase that she will out grow.  Medicine, diet,  and craniosacral therapy have not worked.   She is such a happy kid during the day, full of laughter and smiles.   Where does all this aggression come from that she has to work out in her sleep.  I wish I knew how to help her.
