You can decide it is whatever you want it to be. If any of it is farther from the camera, I doubt it’s dust. It has to be right in front of it to be dust.
And the dust is active right after I leave, or right after I go to bed. Is that how dust works? It’s active right after you leave or go to bed? The heater is off, there is an air purifier on though. Must get windy when I leave or go to bed.
Oops, I forgot to put a watermark on that video. Too lazy to delete and reupload/encode again.
