I have the same problem with clearing my mind. I have talked to CF and others on this and as of yet, even though I understand what they are saying, I am not able to stop this. My mind will just pop from one thought to another with no sense or reason. Even if I try to focus on breathing or ear sound, I still have thoughts flying. It is very frustrating!! I know it is hindering me in projecting (have not had a projection since January). I often have a song in my head also that will just keep repeating.
