What was your prompt? Most of these seem to be related to metaphors for "ideas" or thinking, or having a bright moment.

"Zephyr" and "breeze" might be related to forgetting everything, starting fresh.

So by this way of naive reverse engineering I would imagine your prompt to be "Forget everything and think about a random word". That would prime the LLM to come up with these?

just “a random word” gives you Zephyr in Gemini, and “Lantern” in Claude and ChatGPT.
