To dream of elements that block your progress indicates that you are not very certain you can achieve your goals in real life. You must leave this lack of self confidence behind and not worry so much about what others may think of you. Most likely, due to fear and indecision, you created these obstacles yourself. Often we imagine that obstacles are bigger than they really are. In this sense, it is likely that the impediments that appear in dreams are larger than those in real life.
