Изредка мне хочется всё выключить и просто посидеть в тишине.

Изредка means from time to time, once in a while, or occasionally.

It suggests something that happens not very often, and often a bit irregularly. In this sentence, it sets the overall mood:

• Изредка мне хочется... = From time to time, I feel like...

A close alternative is иногда, but there is a slight nuance:

• иногда = sometimes
• изредка = occasionally / every now and then, often a bit less frequent

So изредка sounds a little more like every once in a while.

This is a very common question.

Мне хочется and я хочу can both relate to wanting something, but they are not exactly the same.

• я хочу = I want
• мне хочется = I feel like / I have the urge to

In this sentence, мне хочется sounds softer, more emotional, and more spontaneous. It suggests a passing inner feeling rather than a firm decision.

Compare:

• Я хочу всё выключить. = I want to turn everything off.
  This can sound more direct and definite.

• Мне хочется всё выключить. = I feel like turning everything off.
  This sounds more like a mood or impulse.

So мне хочется is a very natural choice here because the sentence is describing an occasional feeling.

Мне is the dative case of я.

In the construction мне хочется, Russian treats the person experiencing the feeling as an experiencer, not as a normal grammatical subject.

Literally, the idea is something like:

• To me, it is wanted
• more naturally: I feel like...

This dative pattern is very common in Russian with states and feelings:

• мне холодно = I am cold
• мне скучно = I am bored
• мне хочется спать = I feel like sleeping / I want to sleep

So мне is there because Russian says this as a kind of state happening to the person.

Хочется is the 3rd person singular form of хотеться, which is an impersonal verb meaning something like to feel like or to have a desire to.

In practice, learners often memorize the pattern:

• мне хочется + infinitive

Examples:

• Мне хочется спать. = I feel like sleeping / I want to sleep.
• Ему хочется домой. = He feels like going home.
• Нам хочется отдохнуть. = We feel like resting.

So in your sentence:

• мне хочется всё выключить = I feel like turning everything off

Because всё means everything, while все usually means everyone or all (people/things in plural).

Here are the key differences:

• всё = everything
• все = everyone / all

Examples:

• Я понял всё. = I understood everything.
• Все пришли. = Everyone came.

So:

• всё выключить = to turn everything off

That is exactly what you want in this sentence.

Also note the spelling:

• всё has ё
• in everyday writing, Russians often write все instead of всё, but the meaning is understood from context

In careful learning materials, всё is usually written with ё to make the meaning clear.

Because выключить is perfective, and here the speaker means to turn everything off completely, as a single completed action.

Russian aspect matters a lot with infinitives after verbs like хочется.

• выключать = imperfective = to be turning off / to turn off repeatedly / in general
• выключить = perfective = to turn off completely

In this sentence, the idea is:

• I feel like turning everything off
  not
• I feel like being in the process of turning things off

So выключить is the natural choice.

Посидеть is perfective and often means to sit for a while.

That little prefix по- often gives the sense of doing something for a short time or just a bit.

Compare:

• сидеть = to sit, to be sitting
• посидеть = to sit for a while

So:

• просто посидеть в тишине = just sit quietly for a while / just sit in silence for a bit

This fits the mood of the sentence very well. It sounds temporary, calm, and natural.

If you said просто сидеть в тишине, it would sound more like the general activity of sitting in silence, not one short restful moment.

Просто here means just or simply.

It adds an important emotional nuance. The speaker is not talking about doing something complicated or dramatic, but something very basic and peaceful:

• и просто посидеть в тишине = and just sit in silence

It can suggest:

• no effort
• no conversation
• no tasks
• no stimulation

So просто helps create the feeling of wanting a simple break from everything.

В тишине means in silence.

Here тишине is the prepositional case of тишина.

The preposition в often means in, and when it expresses location or state, it usually takes the prepositional case:

• в комнате = in the room
• в школе = at school / in school
• в тишине = in silence

This phrase is idiomatic and very common. Russian often uses в + noun for states or surroundings:

• в темноте = in the dark
• в одиночестве = in solitude
• в тишине = in silence

So посидеть в тишине is a very natural expression meaning to sit quietly in silence.

The word order is very natural and neutral.

• Изредка мне хочется всё выключить и просто посидеть в тишине.

A rough structure is:

1. Изредка = time expression
2. мне хочется = main feeling/state
3. всё выключить и просто посидеть в тишине = what the speaker feels like doing

Russian word order is flexible, but this version sounds smooth and normal.

For example, you could also say:

• Мне изредка хочется всё выключить и просто посидеть в тишине.

This is also correct, but putting изредка first gives it a slight framing effect: Occasionally...

So the original word order feels especially natural for reflective writing or speech.

It can absolutely be understood both ways, depending on context.

Literally, всё выключить can mean:

• turn off the lights
• switch off the phone
• shut down devices
• stop the TV, music, computer, etc.

But in a sentence like this, it often has a broader emotional sense too:

• shut everything out
• disconnect from noise and activity
• take a break from the world

Because it is followed by посидеть в тишине, many readers will feel that broader sense of wanting peace, quiet, and mental rest.

So the phrase is literal on the surface, but it can carry a figurative emotional meaning as well.
