your brain insisting the world is spinning when really you just stood up too fast
means The unsteady, whirling sensation of feeling faint or off-balance, as though you or your surroundings are spinning.
from From Old English "dysig," which meant "foolish" or "stupid" — the same root that gives us "dizzy." For centuries the word was about a muddled, addled mind rather than a spinning head; only later did the meaning tilt toward physical giddiness. The "-ness" is the familiar English suffix that turns a quality into a noun. It's likely related to similar words in other Germanic tongues for foolishness and confusion — a reminder that a swimming head and a swimming wit were once the same idea.
