Had a dream I was climbing up a steep hill .....?

Hills can symbolize difficulties and obstacles. A steep one would indicate especially difficult obstacles. Warfare can indicate conflict in your waking life. I am glad you are getting help from spiritual forces, as indicate by the white guy who helps you. White is the symbol of innocence and purity and Spirit; orange is the color of the second chakra and has to do with manifestation. Pray and meditate and ask for guidance and help during this difficult time - you will receive it and overcome the difficulties!
