Dream: I have a walking dream. I am trying to find someone or something and I walk and walk miles and never get to where I am going. I met meet people along the way or I might not. Where I walk is never the same place. I feel tired most of the time in the dream after a while.

Interpretation: your dream suggest that you are searching for something - perhaps - something out of your reach - or - something you dont even know how to identify.  You seem to be suggesting that you are on a perpetual quest and it has yet to be quenched with whatever it is that you 'subconsciously' desire.  The fact that you walk miles - is suggestive of your attempts at many things - that have failed - or  - yielded results not consistent with your desire.  Your subconscious is telling you that you are exhausted with the feelings of longing - lack of satisfaction - and - in ability to be content - that is why you feel tired.
