Often there is an open window behind it. Past that, the tradition reads wind as change arriving from outside rather than change the dreamer chose.
A fair number of wind dreams have their cause sitting in the bedroom: an open window, a fan left running, a cold night, or a genuine gale working at the roof tiles while the dreamer sleeps through it. Set those aside and the inherited reading is change, and specifically change that arrives from outside rather than change anybody decided on.
The older interpretations pay close attention to how hard it blows. A light breeze is taken as news, or a small adjustment to plans. A steady wind at the back is taken as circumstances lending a hand. Wind driving into the face is resistance. And a wind strong enough that the dreamer cannot stay upright is the version people remember for years, generally interpreted as being shoved about by something with no interest whatsoever in their arrangements.
One feature sets this apart from nearly everything else in a dream dictionary: there is no object in it. Dreamers describe sound, cold, hair whipping, a door slamming, a coat dragging sideways, but never the wind itself. Interpreters have made a great deal of that invisibility, reading it as an influence the dreamer feels perfectly clearly and cannot point to, which happens to describe a good many waking predicaments.
Wind is not neutral to everybody. Grow up somewhere it howls through every winter and it registers in a dream as weather and nothing more. Grow up somewhere a strong wind means a roof or a harvest is at risk and the same night carries dread with it. Work out which of those two backgrounds is yours before reaching for a general meaning, because neither version of the dream is forecasting weather or anything else.
