Linguists believe that the structure of language is embedded in the DNA. For example, all languages form sentences with subjects, verbs, and objects.
A headier subset of linguists believe that not only are languages embedded, but ideas, as well. As the language evolves, it gives rise to new “ideas.” They are released like bubbles — and form the basis of innovation. They trigger conscious evolution in groups of humans.
This is probably the same as your “id” idea, merely expressed using a different paradigm.
Your image of ideas as bubbles is like dreams released from the subconscious that bubble up through the floor boards of consciousness. I can see your comparison.
