Not exactly. By definition, a dictatorship is a political regime (political system) where a single individual (the dictator) uses his almost unlimited power to achieve his objectives using the citizens of the country in question as mere tools for achieving these objectives.
Using state terrorism and propaganda as the key tools to dictate his will to his subjects. A perfect example of a dictatorship was the Soviet Union under Stalin, China under Mao or present-day North Korea under Kim.
Democracy is the political system where the citizens of the country in question communicate their needs and desires to politicians and government officials and use them as tools to satisfy these needs.
According to these definitions, Nazi Germany was much closer to democracy than to a dictatorship as the ultimate objective of Adolf Hitler (and, therefore, of the whole Nazi system) was to make the citizens of Germany genuinely happy.
Consequently, this system collected information (via an extensive network of informants run by the SD intelligence service and from other sources) about the genuine needs of Germans and used this information to make and implement decisions to satisfy these needs. Thus making Germans genuinely happy.
In other words, Adolf Hitler and the Nazis were servants of the citizens of Germany rather than their masters. And given the fact that the overwhelming majority of Germans (some estimate that over 90%) supported the Nazi regime and had no desire to replace it with a Western-style democracy (or with any other regime, for that matter), they were damn good servants.
