Dictatorships are often found in Communist countries along with Fascist countries
Examples of Communist dictatorships would be North Korea or Cold war U.S.S.R in which case the people were tightly regulated by the government and the government governed by one person with the people having no say in their rights less they be prosecuted
Examples of Fascism would be WW2 Italy and its a debate whether Nazi Germany was more socialist or fascism but for the sake of having it as an example, i would say it was mixed. A fascism is a unified totalitarian government that is intolerent of views outside its boundaries. In other words, its like a big movement or idealogy except that the government is ruled by a dictator.
