How can that be, assuming you were able to learn to read and write, speak and

I see a clue.
If you are hearing individual dots and dashes as separate elements, you're
probably listening to code charaters that are too slow for you.
We don't teach babies to talk and understand speech by speaking v-e-r-y
s-l-ow-ly. We don't expect them to hear "cat" as 'consonant k sound'......'short
vowel a sound'.....'consonant t sound'. Instead they hear "cat" as a unit, even
though it has three parts.
What we *do* when teaching speech is to separate the words clearly.
"The......cat........is.......on.....the.......mat'. So there's lots of
recognition/process time and the words are clearly separated. And we start with a very small
vocabulary, then build on it.
The same principle applies to learning Morse Code via the Koch/Farnsworth
method.
Consider the following thought-experiment:
Suppose you had the task of listening to a series of common words spoken
clearly and distinctly. And after each word, you were expected to write down the
last letter of the word. Would that be difficult?
Receiving Morse Code is basically the same thing except that the words are
replaced by a series of short and long sounds.
