For example, 'I sogni sono importanti' means 'Dreams are important'. 'Sta sognando', on the other hand, is the third person singular of the verb'sognare' in the present continuous tense, which is used to express that someone is dreaming at the moment."}, {"role": "user", "content": "I see, so I would use 'Sta sognando' in a more informal conversation to express that someone's idea or expectation is unrealistic?"}, {"role": "assistant", "content": "Exactly! 'Sta sognando' is a more colloquial and informal way to express that someone's idea or expectation is unrealistic or unlikely to happen. You can use it with friends or in casual conversations, but if you want to be more formal or polite, you can say 'Penso che sia un po' ottimista' which means 'I think he's a bit too optimistic'."}]
