My brain and me - Forever arguing

I have Alexa in the bedroom. She has lots of exciting skills installed including many nature sounds. I particularly like the tropical beach skill which I use to help me drift off to sleep. I try to think I’m on a desert island alone relaxed and with everything I need. Except my brain won’t let me

Me: OK so I wake up in my hammock
Brain: Hold on. When did you get a hammock?
Me: I just did OK and it’s strung under some woven leaves as a canopy 
Brain: Pffttt there’s no way you’d know how to weave leaves. 
Me: Shut up. So I wake up and go down to the waters edge to have a swim/wash
Brain: What about going to the loo? You gonna pee in the sea?
Me: I might. Or I will have dug a latrine
Brain: You know how to dig a latrine? How are you gonna not fall in
Me: there will be a seat of some kind. This is supposed to be relaxing....
Anyway I’m going for a swim
Brain: I wouldn’t. You know what kind of creatures hang out in tropical seas. Poisonous ones that’s what. 
Me: Not in my sea. This is a dream or fantasy, brain. So quit it
Brain: Fine. 
Me: So off I go for my swim
Brain: By the way what are you wearing?
Me: I don't know. Um a crop top and pants
Brain: You're letting the twins hang out? That's brave
Me: I'm all alone. OK I have a no-bra bra-top on
Brain: And pants. On a desert island. So your pant moustache will be flourishing. No topiary kit on a desert island...
Me: OK FINE I'm wearing cut off leggings in a cycling short stylee.
Brain: OK off you go.
Me: OK after my swim I shall go and look for fruit for breakfast
Brain: I have some questions
Me: <sigh> WHAT
Brain: Well firstly, how do you know what fruit is edible. Secondly how do you plan to get up any trees to get it. and THIRDLY...
Me: Well?
Brain: Thirdly, you wont have your medication with you so that lovely Bile Salt Malabsorption will kick in fairly sharpish meaning you'll be needing that latrine on a fairly regular basis. ESPECIALLY if you eat a lot of fruit.
Me: Well the island is full of fruit I recognise and I am able to climb up because the trunks are like palm trees with sort of steps and I will have to cope OK?
Brain: OK I'll be quiet
Me: Good I'm trying to relax here you know. OK So I have gathered a breakfast of breadfruit, papaya and mango
Brain: Um...
Me: What now?
Brain: You know you have no idea what breadfruit looks or tastes like?
Me: I'm using my imagination.
Brain: I shouldn't - That way madness lies...
Me: So then I go and rinse off under the waterfall
Brain: Oh hang on now!
Me: What now?
Brain: How big is this island?
Me: I don't know... small - It takes 2/3 days to walk all the way round.
Brain: OK that isn't going to work you know - Where is the fresh water coming from?
Me: I don't know, under the ground?
Brain: No there wouldn't be enough to power a waterfall and maintain the flow. Either the island has to be bigger or.... Well it just has to be bigger.
Me: Fine it's bigger
Brain: Then how do you know you're all alone?
Me: BECAUSE ITS MY DREAM. 
Brain: OK well if you're going to be silly about it....

By which point I have to get up, google breadfruit, how to build a shelter and a latrine so that I can return to my daydream landscape fully equipped. Unfortunately this has also given my brain time to think...

Brain: Hey um is Saga on this island?
Me: I don't think so - How would Saga get there?
Brain: I don't know, it's your dream. It's just that she'd like to have a whole island to run about on and you need someone to talk to.
Me: Apparently I have you.
Brain: Yeah and look how well that's working out. Seriously I think Saga should be there.
Me: OK fine. Saga is there.
Brain: Great. What's she gonna eat?
Me: What?
Brain: Saga, what's she gonna eat? She can't eat nothing but fruit!
Me: Oh.... Um... Oh shellfish - I will become adept at catching shell fish in the shallow waters nearby.
Brain: That actually makes sense. OK off you go to sleep. I hope there aren't any predators on the island. G'night
Me: <Yawn> G'nighWHAT?????

Perhaps I'd be better off with a thunderstorm...
