My grandma recently moved in with my parents and me after my grandpa's passing away. Almost every night, she talks in her sleep. Actually, she yells in her sleep. And sometimes cries. She yells at her dad and mom (who are no longer alive) and at other family members that are still alive. Not only does this constantly wake up the rest of us while we are sleeping, but she sleep walks also. However, the walking is less common than the talking, it is still extremely dangerous. Just last week, she fell and hit her head and cut her arm while she was sleep walking. My mom and grandma have told her doctor about this and he doesn't seem to really know what's going on or the extent. Can anyone help me in any way?
