Woke up to Scottish tune of song I heard as a child living in UK... and it went on for about 3 hours... maybe I should start writing down what I hear, but then what? Maybe there is a facebook group of those who have this, may be helpful to talk about as even Nurse Practitioner yesterday never heard of it so I have to explain and all the time am wondering if they thin I am making it up!
