You have a good grasp of images that appeal to the mind. I especially liked the lines " A feather of an eagle,/ drifted by, ever so gentle/ into the sky."
But perhaps you need to dwell more on what these images mean to you. What is your poem really about? The images need a plot to make it more cohesive.
The white knight that turns into a bear reminds me of a fairy tale. Perhaps you could retell an old fairy tale, or write your own. Perhaps the woman or dreamer is involved in a quest, and thus all the things you encounter will be meaningful. Good luck with your revision.
