Many great suggestions here. Thank you so much for taking time to reply.

My friend and I have talked at length about mostly everything but she can not understand why loud noises make her feel this way. She becomes a totally different person. So scared and helpless. It breaks my heart to see her like this. She is also a sleepwalker. She tells me it has happened since childhood. She doesnt remember what she does when she is sleepwalking but she does things that could potentialy be harmful. Can the two be related?
