Saying go to sleep in Spanish depends entirely on whether you're talking to yourself, telling someone else to turn in for the night, or describing the physical act of falling asleep. The most direct and common translation is ir a dormir, but native speakers swap between several verbs like acostarse and dormirse based on the exact context.
If you're speaking casually with friends or family, you'll use different phrasing than you would in a formal setting or when putting young children to bed. Let's break down the exact vocabulary, grammar structures, and regional differences so you can use these phrases naturally without sounding like a textbook.
Core Translations: Ir a Dormir vs. Acostarse
When translating the English phrase "to go to sleep," learners often default to a single option. Spanish, however, splits this concept into distinct physical stages: the act of heading to bed, the act of lying down, and the actual transition into unconsciousness.
- Ir a dormir: This means to go to sleep in the most general sense. You use it when talking about your overall plan for the night. For example, Tengo mucho sueño, voy a ir a dormir (I'm very sleepy, I'm going to go to sleep).
- Acostarse: This is a reflexive verb meaning to lie down or to go to bed. It focuses on the physical action of getting into bed rather than the immediate onset of sleep. For example, Me voy a acostar temprano (I'm going to go to bed early).
- Dormirse: This means to fall asleep. It describes the exact moment you drift off. For example, Me dormí leyendo un libro (I fell asleep reading a book).
According to the Real Academia Española, understanding the reflexive nature of these verbs is crucial because misplacing pronouns changes whether you are talking about an action done to yourself or someone else.
Using Imperative Commands to Tell Someone to Sleep
If you need to tell someone else to go to sleep—such as a child or a partner—you must use the imperative mood. Spanish changes these commands depending on how well you know the person.
Informal Commands (Tú)
When speaking to children, younger siblings, or close friends, drop the final s from the affirmative command:
- ¡Acuéstate! (Go to bed / Lie down!)
- ¡Duérmete! (Go to sleep!)
- ¡A dormir! (Time to sleep! / Let's go to sleep!)
Formal Commands (Usted)
When speaking to an elder, a guest, or in a polite setting, use the formal third-person forms:
- Acuéstese, por favor. (Go to bed, please.)
- Vaya a dormir. (Go to sleep.)
Regional Variations Across the Spanish-Speaking World
Idioms and slang around sleep change drastically depending on the country. What sounds natural in Madrid might sound bizarre in Mexico City or Buenos Aires.
In Spain, people frequently use irse a la cama (to go to bed) alongside standard verbs. In parts of Argentina and Uruguay, colloquial phrasing leans toward local slang, while in Mexico, you'll often hear people say irse a dormir or use playful phrases with children like a la cama, a la cama.

Common Mistakes English Speakers Make
Literal translation is the quickest way to sound unnatural in Spanish. Keep these common pitfalls in mind:
- Mistake: Saying Quiero ir a dormir using English word order constructs like Quiero ir a sleep.
- Correction: Keep the infinitive intact: Quiero ir a dormir.
- Mistake: Forgetting the reflexive pronoun. Saying Voy a acostar instead of Voy a acostarme.
- Correction: Because you are putting yourself to bed, the reflexive pronoun -me is mandatory.
Frequently Asked Questions
What is the difference between acostarse and dormirse?
Acostarse refers to the physical action of getting into bed or lying down for the night. Dormirse refers strictly to the moment you actually fall asleep and lose consciousness. You can acostarte at 10:00 PM but not dormirte until 11:00 PM.
How do you say "sweet dreams" in Spanish?
The standard and most affectionate way to say sweet dreams is dulces sueños. You can also say que descanses (rest well) or buenas noches (good night) right before someone goes to sleep.
Can I use "dormir" by itself to mean "go to sleep"?
Not usually. Using just dormir means to sleep (the state of resting). To express the movement or transition of going to bed, you need reflexive structures like irse a dormir or acostarse.
Is "suenia profunda" correct Spanish?
No. The correct spelling is sueño profundo, which means deep sleep. Suenia is a misspelling that mixes up verb conjugations with the noun form.
