Spontaneous movements

I have been experiencing some spontaneous rocking/swaying/oscilating movements of my torso sometimes while standing,more so when sitting. These movements are unpredictable and small. The change with the breath constanly evolving and adapting. I can reduce these movements or give myself over to it. I feel like reducing the movements is interfering with a process that should be happening. Sifu, you talk about non interference. Is this something that I should be  experiencing and allowing to happen? Is this to be expected? Is this a natural balancing process?
