It would seem like it is Starbuck..as you say letting go of old patterns. However i can't help but get a sense of you having an idea, a dream or emotion that you want to get out but are afraid to do so. Possible fears of being attacked by ridicule maybe? The two officers hitting the head of the person seems like the more repressed your ideas are the more struggles mentally. Like in a sense it is an imprisonment. The lady in your dream. I pick up that this is you almost forcing yourself to see the gap you yourself create in not letting the 'birth' of liberation come out along with the new beginnings. What things hold you back you could ask yourself. The squeezing could be the surpressing of whats in that needs to come out.
Hope that helps.
