K.F.
My mom was just talking to me about this the other day. I would do the SAME EXACT thing, around 3-4 years old. She almost took me to the emergency room the first time it happened, she thought there was something seriously wrong with me. I guess they are called night frights..I also started sleep walking around that age too. I would lock myself in the bathroom, try to leave the house, walk around in circles on my bed and have full on conversations with my mom to where she thought I was awake but she would eventually realize I was actually sleeping.
