It's weird how we say "go to sleep" as if sleep is a place

One night my daughter asked me, "Where is dreamland?" I explained that it's a made-up place you think of while you're asleep, and how everyone has their own. Little kids take things so literally, when we talked about "going to dreamland" at bedtime she probably wondered if it was an actual place she went somehow - but where could it be? Great question.

I think I believed that for a time when I was a kid, that dreamland was a physical place people went to when sleeping

We "go" to lots of things that aren't places. Im going to prove it with this sentence.

Let's not go off the rails.
Can you do it after we go to lunch?
- ...into space. go figure
In English, ‘go to’ can be used as the future subjunctive tense of the verb being conjugated.
- Sounds fancy. I hope it's not expensive to use.
Planning to go into detail, or was that it?
Go to ass.
- if you insist ;-)
I've got to go think about it for a second, and then I get to realize what it meant.
I'm going to go to sleep.
Double going!
Different usage. You wouldn't tell someone "Go to prove." Are there any examples of "Go to [word]." where the [word] is not a physical place?
- Yes. We regularly say "go to [verb]".
  Go to eat
  Go to learn
  Go to exercise
  Saying "go to sleep" is exectly the same.
- Not many.. Heres what i came up with though:
  Go to great lengths
  Go to extremes
  Go to bat for something
  Go to town on something

you don't go places when you sleep?

As a stress sleepwalker, yes I do.
I wish I did, I don't dream so for me it's pretty much just skipping anywhere from 6 to 10 hours and suddenly it's the next morning.
I sure do. Just last night, I went to a store that was closed. The shopkeeper had hired a very tall and furry troll to guard the store at night. She said the shop is closed, and seemed a bit irritated. We shook hands for no apparent reasons, and then I went away. I sat into a car, we drove off, accidentally drove off road, plowed through the 1 m thick snow, fell off a cliff. We nearly crashed into a house, but somehow managed to land on a road right next to it.
That’s why you don’t try to do your shopping in the middle of the night.

In Spanish, they talk about hunger and thirst as if they are physical objects.

I think that's more that tener (to have) doesn't always mean a physical thing.
As an example in spanish they use tener for age. As in tengo 20 años literally is "I have 20 years" but it means "I am 20"
Or ten cuidado means "take care" or "be careful" but literally is more like "have care". Both phrases use tener in a nonphysical sense in the same way as in english we use "to have". Like to have compassion or to have doubts.
- but it works because abstract concepts are things an individual can own.
  Like "Tengo quidado" is "i own the the abstract concept of care".
  it could work in English, but it just sounds strange or poetic, like "i have hunger"
German too. Ich habe Hunger. Sie haben Durst.
- Sie haben Durst
  Durst
  Heh, Fred Thirst
- You can have feelings too.
Je suis Francais. J'ai froid. Je plaisante, j'ai je suis chaud.
Feelings are things we have.

The void calls ceaselessly, child.

If you have trouble going to sleep then try falling asleep instead.

In Dutch “go” means to go do a thing as well and I use it English in a similar fashion. Never thought of it weird before

Edit-preface: I am not a grammarian. I don’t know what the technical names for the different types of “to” are or if they are even recognized as distinct by experts in the field.
English is does indeed use “go” to mean “go do a thing”, but not with directional “to” (as in “go to the library”).
“Go run!”, “Go running”, “I’m going running”, and “I’m going to run” are all valid uses. (In that last case, the “to” is not a directional “to”, but is actually part of the infinitive verb “to run”, as in “I want to run”). However, you wouldn’t say “Go to run!” to tell someone to run.
"Go to run" could make sense with a causal “to” (“Go, in order that you might run”) but that separates “go” and “run” in to separate actions. Causal “to” is the “to” in “push to open” and “press F to pay respects” this is not the “to” in “go to sleep”
“Go to sleep” feels like it is in the directional sense, like "go to bed"
Edit: Now you’ve got me thinking. “Go to sleep” and “go to bed” are a little unusual . “Go to [location]“ without an article is usually reserved for proper nouns or pronouns (“Go to France”, “go to Curicó”, “go to Walmart”, “go to John“ “go to her”). When the location is a general noun, you usually use an article or a proper/pro-noun in the possessive form (“go to a restaurant”, “go to the party”, “go to Bob’s house”, “go to your room”). So what makes “bed” and “sleep” so special? The only other case I can think of at the moment is “go to ground” and that is different because it is an idiom, and the rule for idioms is “they mean what they mean”
Edit-edit: meals don’t use an article either: “to lunch”, “to dinner”, “to breakfast”.
Edit-edit-edit: AAAAAH! It applies to some other prepositions too: “in bed”, “at lunch”; but not “under the bed”. What is going on‽
Edit-edit-edit-edit: Causal “to” might be a use of the infinitive case?
Edit-edit-edit-edit-edit: “go to work” does not use an article either.
- Damn that’s a good write up!
  Another thing we say often in Dutch is I go to bed. Which works in English too! “Ik ga naar bed”
- I think it's because the "to" in those phrases are part of "to sleep" not part of "go to". The "to" modifies the verb "sleep" to be an infinitive and the "go" is an imperative verb.

Well then take a piss.

I'd rather leave a piss.
Go poop.
- That's what i say in the bathroom, like it's a team sport.
  Goooo Poop! 🤾🏅

I wish it was. I wish it was...

I'm going to go, to my bed, to sleep.

The word "go" has lots of meanings besides physically moving to a place. It also means to change state ("the milk went bad", "he'll go crazy when he finds out") and to indicate immediate future tense ("I'm going to read this book now"). Not to mention some other less relevant uses.

It's a state.

Yeah I think it's going to make me go insane

I'm 90% sure that it was originally in the form of "to go <there/place> and

<verb>

" and has just been shortened over time. A refined colloquialism, if you go for that sort of thing

Sleep is my go to when I'm tired!

The Dreaming

In german we say either say "go" or "laying to sleep/rest"

Huh that's funny, "laying to rest" in English is an expression for burying someone after they have died
- Yeah we also say "they are not yet under the world of the living" if someone is still asleep
- We also call the event of publicly watching soccer matches etc. "public viewing" so...

Naw, just a state of mind.
