I'm going to guess you've never had an extreme problem in communication throughout your entire existence.
For some time, for me, the grammatical structure of my sentences formed such a weak relationship to the interpretation of meaning of language, that a single word of a single sentence in a single paragraph could compose many meanings, and that doing this over and over throughout the paragraph could compose many more meanings, until all comprehension of what was intended to be expressed seemed to be completely lost. Communication had distinct dual meanings often, sometimes many, many more. The grammatical structure serves as an abstract form, then each word relationship is applied and toyed around with until associations that have nothing to do with the topic at hand are formed. I would be lost in attempting to speak back to someone. When I tried to speak, I would run off on a tangent that received blank stares at best. I was convinced people were purposefully messing with my head, but it was only the extraction of a single word from a single sentence that projected itself into my imagination and then distorted itself into a web of intricate knots that continued to build one after the other.
Some people call this telling stories. For me, it was the way I perceived my reality, even though my perception held in thought never matched my reality.
I have a habit of escaping into complex mathematics, so at least I have the illusion of intelligence (although it turns out, I am very good at complex mathematics, and this is useful). But it's very difficult, living like this. The single and the many is a real problem. You can think you know what you are talking about, but until you actually become convinced that every sentence can be interpreted completely differently by the listener, and by some form of magic I call compassion of others noticing how completely aloof I am, you manage to exist in society as member that actually contributes something. Also, when you intersect with people really frequently over short gaps that are spaced out by really long gaps of 'misunderstanding one another', then it's freaky and causality gets all tangled and you can sometimes get convinced that people can read your mind.
You may say cloud, but when I first read this article, I thought of the internet clouds, instead of water clouds. Now, this is only a small delta change between word choice. Imagine that a single sentence can be interpreted in millions of ways, and it can be continued on in conversation, in other sentences in millions of ways, and no one actually has a clue of what is being spoken about, but we all think we do. This is why I prefer to stare at my whiteboard with complex mathematics.
