This is actually more than one question but they are connected, I dont know how to post them separated and make sense.
I was reading a translation of ゆめの続きはどこだ!? as "Where Does the Dream Continue?!
Now I knew one of the use of の is similar to the "'s" of english. But the "'s" is used only with nouns and here it's used to connect a noun with a verb. is here the verb used as a noun and a more literal translation would be "where does the dream's continuation is?" and the translation was adapted to sound more natural? (correct me if I'm wrong) . And the other question is, when I want to join a noun with a verb with the の particle, do I have to put the verb in infinitive?
