I morse, jag sprang jag lite och hadetog en liten dusch efteråt.

“I morse” is an adverbial phrase, changing the following word order to VSO.

Då, jag åt en dal skål av stålskurenSedan åt jag en [?] skål havregrynsgröt på havrekross, vilkent jag äter varje morgon.

1) Ditto. 2) ”Then” is divided into two adverbs in Swedish – “då” meaning “at that moment”, and “sedan” (or “sen”) meaning “after that”. 3) Not sure what “dal” was meant to be – let me know! 4) The preposition for “containing” is either “med” (“skål med havrekross”), or, more elegantly, elided entirely. 5) Steel-cut oats are called “havrekross” in Swedish, but it doesn’t refer to the oatmeal made thereupon. More common would honestly be to say “en skål steel-cut oats” as a loan word. It’s a trendy dish! 6) “Vilken” is indeed correct for “skål”, but that would mean you eat the exact same bowl. “Vilket” stands in for e.g. “Ett mål mat”.

Senare, under lunch, jag lekte spelled jag Boktai på min GBA medan ute på min balkong.

“Leka” is used for playground games, rather than board or video games.

Jag hade ville lekelat spela det förra sommaren… men gjorde inte det!

I kväll, ska jag kommer att ase på en ströeam av någon sorts lLaserdDiskc min vän fanthittade.

1) “Kommer att” would not be wrong, per se, but “ska” more commonly indicates intention. 2) “Stream” is just a loan word in Swedish. 3) As is LaserDisc… or at least I’ve never heard anyone say “laserdisk”! 4) “Fann” is fairly formal; “hittade” is more typical in casual speech.

Det bör varabli kul!

Since it’s in the future. With “vara” it reads as “it should be fun” as in “it is a moral imperative for it to be fun”, as opposed to “it will most likely be fun”.

TillHörs imorgon!

Just an expression that doesn’t exist in Swedish.
