My repeating dream

Maybe someone would have an idea about my dream:
I am in a big town with old timber striped houses and I seem to recognize it all. It is of the present time, but nobody knows me as I walk the streets endlessly alone.
I meet this town in many dreams over a long period of time. It is a big old town in the snow top mountains and right by a big lake, where there is a church on a little hill.
Every time I dream of that town now - I think to myself " Oh no, not again!" I feel homeless and alone althought I know the town.
I have had this dream even before I emmigrated to Ireland from Denmark. The town of my dream is of none of those 2 countries.
