Is the building your home, or feel like it's a familiar place of being? Are you in a situation you feel you can't get out of? The circling can represent the incessant chitta of the mind that is trying to fathom a way of resolving an issue. Are you trying to find the courage to move forward in your life but can't? Is procrastination one of your enemies? Are your current circumstances not to your liking and going against what you innately want?
A lot of questions to ask yourself and hopefully you can shed some light on your circular experience.
