Back in front of my PC after my weekly trip to the shop. Oddly calm in the morning the last couple of days. I think it’s because I’m slipping back into the lockdown peace, no stress, nowhere to go, nobody to see, just my own peaceful life. Won’t last, of course it won’t, it can’t, at some point the world will wake up and I’ll be forced to deal with it again, but not now. Can’t believe it’s only a week since I took the van out, it feels like ages ago.

The sun is shining at present. I didn’t mow the grass when I said I would – maybe I will today, if it stays sunny, though it must still be wet underfoot.

I’ve not been remembering my dreams recently. When I wake up, I know that I’ve been dreaming and now I’m awake, but the content of the dream is completely gone from my awareness. It’s like watching something on the telly, and you know you haven’t been asleep, but you haven’t got a clue what just happened, or what was said, and you have to rewind the last few minutes to find out. Of course, that also happens when I’m listening to the radio, or reading, or even in the middle of a conversation (though in that case there’s no rewind button), and as I now know, that’s all part and parcel of dyspraxia. But I’m sure I used to remember my dreams.

Incidentally, although for me the lack of short term memory had always seemed to be the key aspect of dyspraxia, from which all else follows, it’s only recently that I’ve started to think it might be the other way round. Starting from the premise that it’s due to faulty message processing in the brain, and that that makes it hard to focus on more than one thing at a time, this leads to the phenomenon of ‘absent-mindedness’, whereby I have no recollection of where I put my glasses, because when I put them down no part of my brain was processing the information : ‘I am putting my glasses on the bookshelf/back of the toilet/behind the fruit basket/they just fell on the floor’ and so doesn’t leave an imprint on my memory.  

Sounds like a good theory – it definitely reflects my personal experience, anyway. I expect somebody somewhere has thought of that before, but as I mentioned yesterday (I think), my PhD supervisor pointed out years ago that I struggle to accept things unless I can understand them from first principles. What I don’t think he understood at the time was that it wasn’t due to bloody-mindedness so much as that my brain couldn’t hold and process that information if I didn’t have the right pegs to hang it onto. Which sounds quite paradoxical, because although I can have enough flashes of insight to have achieved a PhD, there are times when my brain freezes and I’m incapable of absorbing what I’m being told.

Another morning, another empty white screen.

Still reading that book. It’s moved on from left brain thinking to ways of developing the right brain: yoga, tai chi, meditation etc. The irony is that my PhD thesis was all about managing a world where causes are reductive and impacts are holistic. Trying to find left brain categories for right brain phenomena when language itself is suspect because it immediately binds thought into its own limitations. I used to get so excited about all that stuff, until I realised that this is in itself the problem, that the two can never be reconciled, and that’s why the world is in such a mess, and probably why my head is in such a mess too. I didn’t use the language of left-and-right-brains twenty five years ago, but the ideas are directly comparable.

How can I express myself more clearly? Reading back that last paragraph, I thought: it’s about control. We try to understand causes and control them, but the problems with this are legion: how do we identify the fundamental causes? How do we find ways of controlling them? How do we implement the controls and sanctions? How long does it take before we come up against the unintended consequences of those controls and sanctions? And what has happened in the meantime to the overall impacts we were trying to control in the first place? I could go on, but I’ve probably confused you more than enough already (if there is a ‘you’ still reading this).

And how, if at all, does this relate to my dyspraxia? The author of that book would probably say that my right brain is currently working out something that my left brain is preventing me from recognising.

Yesterday was Skype-therapy day, I read out to the therapist the list of ‘wisdom’ bullet points that I posted earlier in the week, and I thought I was being quite tongue-in-cheek about it, but part way down the list I started to get tearful. Because all those contradictions and over-simplifications are what makes up who I am, and can’t be wished away by well-intended platitudes, or by trying to make me laugh at myself when all I want to do is cry. Maybe, in the context of what I was saying, they’re a set of left-brain ‘solutions’ to the holistic right-brain question of who I am and how I get by in this world without shattering into a million fragments.

I’m not saying dyspraxia explains all of that. Of course, it’s a left-brain category and hence by its nature draws arbitrary lines in the sand – this side and that side, inside and outside. But the more I look into it, the more I unravel the strands of how I became this self-contradictory person, the more I can see how well it fits.

Yesterday I joined a Facebook group for dyspraxic adults. I have a sense of ‘coming out’ and being – not exactly proud (I don’t do ‘pride’) but maybe ‘honest’.

Memory plays funny tricks. I’ve been transferring some of my old cassettes onto the PC, via a USB cassette player, bought for me by ex-hubby as a Christmas present, but which has spent most of the last decade stored away in its box. I haven’t been doing it the last few days – since the weekend in fact – because I realised the rooms on either side of my study were probably used as bedrooms and I didn’t want to disturb my neighbours too early in the morning.

But when I sat down this morning I had Joe Jackson’s ‘Breaking Us In Two’ in my head and thought: I don’t want to copy anything this morning, just do what I normally do, which is to shuffle the list and let Windows media player go randomly through my music. But when I opened it, the song which started up was ‘Breaking Us In Two’, so presumably it was the last track played and had stuck at the back of my mind from four or five days ago, or whenever the last time was that I sat here with music playing.

I started writing yesterday but everything I was thinking was so dark that I didn’t really want to go on. Feeling much the same again today. I think I am coming towards the time when this all seems so overwhelmingly futile that I give up altogether. ‘If you can’t think of something nice to say, don’t say anything’. It’s been quite a good run: four months, roughly 120 days (barring those I missed), 60k words.

‘I’m reading a book which puts forward evidence from research in neuroscience to show that what we call the ‘self’ is not single and fixed for any individual but rather plural and malleable, and hence, in a sense, illusory. I don’t find this contentious, in fact I’m rather surprised that anybody would. It’s rather like saying ‘there’s no such thing as society’ – there may be no specific institution or body which bears that name, but the influence of the web of interactions, rules, structures, relationships etc on the actions of people and organisations leads to impacts in the physical world.’

That’s how I started yesterday, which I suppose isn’t too grim, but the rest of what I was thinking was. I read some more of the book after that, and found that the author was saying that the ‘self’ is created by contrast with everything which is outside the self. Which surprised me, because there I was thinking the other way round, that it is embedded in a network of influences (nature and nurture) and is the product of those. I’m not a psychologist, and maybe I’m not understanding the terms properly – what’s the difference between the ‘self’ and the ‘personality’, for example?

He went on to say that the left brain operates by looking for patterns and telling stories. Which sounds very like me.

Maybe I will keep writing – at least, when I’ve read some more.
