To see that an obstacle like a wall or a curtain appears in front of you while walking on a boulevard and to see that you cannot continue on that path is a sign that you will not be successful in the job you started. Seeing that you are on a long boulevard surrounded by tall buildings on both sides is evidence that you have given up on what you thought and wanted to do.
