The bed is very heavy: imagine it like a Transformer between a wardrobe and twin size bed: https://imgur.com/a/L7M1WmA
Since in my country in Southern Europe these kinds of walls in use here in Sweden aren't very common, I would like to know which kind of wall plugs (dowels) should I buy to fix the bed to the wall.
A metallic "plugg"?
How many centimeters long?
Do you have an example link or name/image?
The bed itself provides two metal plates which 4 holes each (0.6 cm) but leaves to the customer to purchase the plugs according to the wall type: https://imgur.com/a/GCOgkHz
If the wall is concrete you should use suitable plastic wall plugs. Check out Fisher SX for instance, it is a common, good, wall plug. Under documents you can find the load table which says that SX 8x40 can bear a load of 0.7 kN (i.e. appx 70 kg). When attaching the screws so close to one another you might have to derate that a bit but probably not in concrete.
Another example is the ESSVE N 8x40. Check the "Broschyr" at the bottom of the page for load capacity. The N8x40 can take a pulling load of 80 kg. The minimum drill depth is also given by the same table.
The practical loads will be nowhere near this because of the construction of the bed cabinet, but do use all of the holes when affixing the bed to the wall.
As for screws, use a good quality 6x50 mm wood screw
As a future tip, upload the images directly to the forum, it's easier to look at them inline than to follow links.

Thank you for taking the time for helping me out!
Instead of the nylon plugg, what about a bunch of metallic EXPANDERSKRUV M6 (6x50) instead?
I think that this will bring to zero the chances that the bed collapse on you after few months of pulling.
There are also a variety of different concrete screws that go directly into the concrete. They will work absolutely great in "new" (read:not 50 Y/O) concrete, which your walls consist of.

Thank you for your answer!
Exactly to what I was thinking of.
It's better to spend even 50-79kr for each metal expander but be 350% sure that the bed will stay there no matter what.
If I look at the kN of the EXPANDERSKRUV M6 (6x50) mentioned above is 2.8... that in kg means 285!
8 of those and my bed doesn't go anywhere not even in 10 years from now

You're absolutely right. However, what I meant, was proper screws. If you google "betongskruv" you'll get plenty of hits. "Lättbetongskruv" are something completely else though, and I'm sure they'll show up in your hits as well.
I would advise against metal expanders since they are annoying to remove. You have to use an angle grinder or equivalent and cut them flush with the wall. There is no chance that your bed requires that amount of fastening.
Concrete screws are somewhat tricky to find in small dimensions. If the holes in the fastener are 6 mm you should probably be using a 5 mm screw which seems to be difficult to find. Using a nylon plug also gives you some wiggle room with the holes if they are not perfectly aligned, as opposed to concrete screws.
I have been thinking about buying the same murphy bed for my 24 sqm apartment. It would be nice to have some more space in here.
If you could leave a review here or in another thread after you put it up, that would be much appreciated!
In my case the bed would either have to be mounted to a brick wall or a wall made by a mix of cencrete, news papers, wood and "hönsnät" (don't know what the name of the method is).
Would I use the same plugg as rvf for the brick wall? Is it even possible to mount anything to the other wall?
Here are some pictures of the brittle news paper wall:

I spent only a couple of hours searching on the major DIY chains in Sweden (Jula, Clas Ohlson, Bauhaus, Biltema, Beijer...), but the minimum size that I can find betongskruv is 6 mm. Something like this:
Can't find how many kN this one can tolerate.
ESSVE has some betongskruv as well (6.3x50), granted for 80 kg, but perhaps they don't fit into the sängskåpsbeslag, and they are only available online.
Also screws made by big brands like Fischer seems hard to find in the chains...
Some betongskruv are also described by the manufacturer to be not adequate for load-related activities, so one has to really go deep into the specifications of the screw (if they are available..).
