One-pointedness and bigotry are not qualities that are particularly spiritual, but self-discipline may require us to keep to the ?straight and narrow?. A narrow bridge might suggest a difficulty in communication, perhaps in putting our ideas across. We should take care not to be narrow-minded and judgemental in our dealings with other people. We may be intolerant and parochial in our opinions.When we dream of anything that is narrow, we are aware of restrictions and limitations. Sometimes we have created them ourselves, sometimes other people will have created them for us. A narrow road would perhaps suggest some kind of restriction, and a warning that we must not deviate from our path. A narrowboat highlights the meaning of a boat with the tendency to put additional restrictions in place. You might like to consult the entry for Boat/Ship.
