I'll start by saying that this is currently just a wall of text. Just because it's short, it doesn't mean it shouldn't be separated out into different paragraphs. It makes it easier to read and understand.
There's some SPAG issues that I'll point out to you. I believe you're trying to type as someone may speak, but people rarely do that in real life, honestly. With me, the occasional 'ain't' may slip out in my typing, but there's a huge difference between typing (where I can think and delete things) and speaking, where I sometimes slip into my native accent.
Honestly, things like dropping 'g's and issues like that don't give your text anymore personality. If it was dialogue, sure - it gives an element of personality and a specific accent to a particular person. But in this first person, diary-esque writing, it just seems hackney and unneeded.
Bloody fuckin hell.
'Bloody fucking hell' or, 'bloody fuckin' hell'. If you're going to insist on removing the g, then you should still include the apostrophe. It's not clear why/what form the character is writing this, and it doesn't always have to be, but purposeful grammar/spelling mistakes that are coming from your character and not you as an author need to be more clear.
I must be losin it.
'I must be losing/losin' it'.
But if you work at where I do, of course you'd be a little loony.
Okay, so they're writing this down…why? I mean, The Foundation - and hence its personnel - are as secretive as possible. Even if this were some sort of personal diary, I would find it hard to believe that they would record that their job was enough to make them 'loony', and to possibly kill them. Can you imagine if someone else came across this?
It's also fourth-wall breaking - assuming they are writing this to themselves, they already know where they work, so they don't need to include anything about it.
A single blink could mean a death sentence.
Is the subtle-not-so-subtle reference to one of this Wiki's most famous articles really needed?
"Fuck you to"
'"Fuck you too"'. The further I read, the more these spelling errors are seeming less likely to come from Foundation personnel, who have to have some degree of literacy to keep their job, considering they have to do things like report-writing. If they are the character's mistakes, this still isn't clear (just like who to or why they are writing in the first place).
For some reason, I went through all that without breathing, and just now start to suffocate. I'm alone in space, drifting along.
So how are they recording all this? As I keep saying, what form this is in isn't clear.
Then the fucking space monster thing comes in front of me, and opens it's mouth. And then it goes dark.
Yet they're able to keep recording?
In terms of context, this is rather dull. There is no character to get attached to, to care about if they live or die. Someone having anxiety dreams that may or may not come true is an old trope. It doesn't mean it can't be used, but I think the idea of nightmares, inability to sleep (vs. the less human seeming ability to sleep) etc. has been mentioned quite a lot when it comes to The Foundation. You're not offering anything interesting for the reader to grab hold of, such as a relatable character who has an arc (even in a short story, this is entirely possible). As far as the potential scip goes, it's just an alien or creature of some sort who kills for no reason. Just as it shouldn't be done with an article, nor should it be done with a Tale. There's also the ongoing mystery of 'just how are they recording this', especially after they were most likely gobbled up by said space creature.
There isn't a lot redeemable here. I don't feel anything for any of the characters (everyone has nightmares, it doesn't really invoke sympathy when written in such a short form) and I don't feel anything for a scip that kills people for no reason.
ETA - I realise I say 'writing' a lot when they could have been recorded. However, that accounts even less for the SPAG mistakes if this were typed up by someone who somehow found this recording, and still doesn't make sense in a lot of areas.
