Explanation:
The word "se" has many uses in Spanish. Two of the most frequent uses are the impersonal "se" and the passive "se". The impersonal "se" is used with a third person singular verb to express the impersonal English subjects, one, you, people, or they.
The passive "se" is very similar to the impersonal "se". The agent of the action is either unknown or unimportant and the influence is placed on the action and not the doer/actor.
The impersonal se:
In some sentences, se is used in an impersonal sense with singular verbs to indicate that people in general, or no person in particular, performs the action. When se is used in this way, the sentence follows the same pattern as those in which the main verb is used reflexively, except that there is no subject to the sentence that is explicitly stated. As the examples below show, there are variety of ways such sentences can be translated to English.
Examples:
Se maneja rápidamente en Panamá.
People drive fast in Panamá.
Se puede encontrar jabón en el mercado.
You can find soap in the market.
Muchas veces se tiene que dormir para relajarse.
Often you have to sleep to relax.
