I'm sorry but you personally don't what on a foam mattress? You left out like the most important word of all of your comment. Don't mind, don't like, don't love, don't prefer?
It can be guessed from the context but still.
Recently, I even wrote "buy" instead of "by"! Crazy times
I think it is an advanced state of distraction that causes it, a brain unable to really care about anything until the next dopamine hit.
[0] the intentionally missing word is "true"
[1] the intentionally missing reference ([0]) is after the word "so"
[2] there are no more omissions
It's just something occasionally goes wrong with the thought -> word pipeline buffering in the one case. I find the homophone substitution more interesting - I would never, ever make the mistake writing, or if I was paying attention to what I type (I find it happens even more commonly if I'm not paying attention to the window I'm typing on), at some level it seems that the unconscious word-to-keyboard process 'hears' and transcribes somewhat phonetically in a way totally disconnected from my conscious thought process. I find it fascinating I can 'visualize' the spelling of and think a word like, I don't know, 'bare', but my hands, as if completely independent, type out 'bear.'
Another piece is that, if someone talks to me while I am typing, sometimes words from our conversation creep into the text.
Interestingly, I find these mistakes are more common when I am taking stimulants (caffeine) than when I am not.
[1] This is another common mistake I've noticed. I am quite certain I thought 'reduced', but 'reducing' came out anyway. I think this is usually due to me changing the grammatical structure of the sentence midstream; I probably originally thought "you're reducing" instead of "you've reduced", but I typed faster than the thought completed. Maybe this says something about my intellectual capacity. :)
also, i tend to agree with your conclusion, i think what i described are normal human errors, not necessarily signs of dyslexia.
