I want mountains, seas and freedom. What do you mean by joking?

I want mountains, seas and freedom, and jokingly express my yearning for an ideal life. I want mountains, seas and freedom. I'm joking about an online buzzword, which comes from the lyrics of a song "The Most Familiar Stranger". This sentence means to express a yearning for an ideal life, but it is unrealistic, so I added a joke to laugh at myself or ridicule. This sentence can also be used to express your love or dependence on someone, but you don't want to say it directly, just use jokes to ease the atmosphere or cover up your mood.
