Dreading Dreaming

Perhaps this is a problem. Perhaps not. I've been having dreams about my D.A.D.S.. Really terrifying ones. 2 days in a row I dreamt of him. Then it went off and on. Waking up in tear's because one nightmare was so bad is a problem. I wish that it'd stop. But what am I supposed to do? I don't wanna dream about my D.A.D.S. threatening my family and coming to kill me. This sucks. :(
