I believe that "niba" / "hitnabé" meant "to be crazy"/"to emit crazy things" in ancient Hebrew: https://en.wikipedia.org/wiki/Nevi%27im - including in today’s casual sense or "to seek divine guidance". Initially, most of them were out-of-control Schizophrenics and maniacs but eventually many of the best Nevi’im were hypomanic at worst, and not only emulated their predecessors or contemporaries but topped them.
They could have been funny, or exalting, or sexy, or blasphemous. They often spoke in normal prose or free-form verse.
Ezekiel chapter no. I - https://www.chabad.org/library/bible_cdo/aid/16099 - can be seen as mocking the various previous visions-of-revelations and doing it so well that people found it incredibly funny (and it is pointless to derive meaning from it - Ezekiel was just "making shit up").
