Learn Russian: Из-за тревоги мне совсем не думается. Я просто хочу уехать на море. - Because of anxiety I can't think at all. I just want to leave for the sea.

Мне не думается is an impersonal involuntary state. While я не думаю just means I am not thinking, using the Dative pronoun (мне) with the reflexive verb (думается) implies that you want or need to think, but you can't. It expresses a lack of control, like thinking just isn't happening for me.

Can I use this Dative + reflexive pattern with any verb, like мне не уезжается?

No, this pattern works naturally with a limited number of imperfective verbs, mostly related to basic physical, mental, or emotional states. Common examples are мне не спится (I can't sleep), мне не работается (I can't get any work done), and мне не читается (I can't focus on reading). It sounds unnatural with specific action verbs like уехать.

Why do we use на море instead of в море here?

In Russian, going to the seaside for vacation is traditionally treated as going to a surface or territory, so we use the preposition на. If you said уехать в море, it would sound like you are literally going into the water or sailing out to the open sea on a ship.

Is на море in the Prepositional case here?
