This happens to me sometimes. If i am in the middle of a discussion at my thrapists office and I start to feel overwhelmed...(and it happened the other day when i was in a restaurant) with a friend. A song will start to play in my mind like "breathe"' "just breathe" by Faith Hill. I have other songs of words but i am too tired to remember. I know it makes me feel and sound like I am crazy? Does anyone else experience this?
