Questions & Answers about Я мечтаю поехать к морю весной.
What does the verb мечтать express here, and how is it different from “to dream” while sleeping?
Мечтать means “to dream” in the sense of longing/aspiring for something in real life. It’s about wishes and desires. Dreaming while sleeping is expressed with видеть сны or (мне) снится (e.g., Мне снится море = “I’m dreaming of the sea in my sleep”).
Why is it поехать and not ехать?
Поехать (perfective) focuses on the single act of setting off/going on one trip. Ехать (imperfective) describes being in the process of going. With a wish like this, Russian typically uses the perfective infinitive to mean “(to) go (once).” Мечтаю ехать would sound like you dream of being in transit rather than making a trip.
Could I use съездить instead of поехать?
Yes. Съездить is perfective and adds the nuance of a round trip (go and come back). For a vacation, many speakers actually prefer съездить: Мечтаю весной съездить на море sounds very natural.
