My sister has in just the last couple months began talking in her sleep and more recently has begun yelling out during the night from dreams. It is becoming more frequent to the point, she dreads going to sleep. Last night she was screaming loudly and her husband woke her and said she also was kicking her legs frantically! She remembers the dreams and they are mostly some fear she has, (snakes, attacks) but not all are like that. Anybody ever experienced anything like this?
