Unable to remove Grey bar on page

On only one of my pages, I have a large grey bar that I am unable to remove– immediately below the navigation bar and before my posts. I tried comparing all the settings on my other pages, but cannot find the setting difference for this page set up and would like to remove the grey bar as it takes up a lot of space and makes it more difficult to see the posts: http://www.dreamsisterspuna.com/dream-symbols/

Thank you so much–
