As a child, I sleep walked to the door and tried to open the door. Was stopped by my late granny. She said I did this > once.
DD sleep talks. She slept with us when she was younger. Imagine in the middle of the night you hear a little child's voice whispering away and giggling. Sometimes she will sit up and talk, all the while still asleep with her hair all over her face.
Late FIL say this one inherited from DH. DH talked so loud in his sleep that PILS thought someone broke into the house he was quarrelling with that someone in the middle of the night.
