"gana" is basically desire/inclination. A phrase such as your "tener ganas de hacer algo" can be translated as "to feel like doing something" (in fact, this would be the most likely way to express the idea in English) but could also be translated as "to have the desire/impulse/inclination to do something". The latter is not "normal" English but more closely reflects the syntax of the Spanish expression.
It is often the case that the "best" translation is quite different grammatically/syntactically but best conveys the "meaning".
son las ganas de cambiar la realidad is basically pasive voice (someone or something desires).
eres mis ganas de revivir is You are my desire to relive.
