To dream of morse code represents an exhausting attempt to communicate to someone else when nobody wants you talking to them. Attempting to outsmart someone nosy, overbearing, or controlling. Attempting to get away with something to someone else’s face by disguising your true intentions in plain sight.
Negatively, morse code may represent a naughty or underhanded disregard for authority. Going to elaborate lengths to hide talking to people you have been told not to.
