Yes, absolutely seen this. My old cat Misha used to go completely rigid and stare at a corner of the bedroom maybe 2-3 minutes before anything happened. Not tracking movement, just locked onto one spot. Then something would shift - a book, a glass, whatever.
What gets me is the timing. Its not random nervous cat behaviour, theres a clear pattern if you pay attention over weeks. I started logging it after a while and the correlation was hard to ignore.
My current theory is animals are picking up on whatever precursor energy or field change happens before the physical effect. Like an early warning system they didn't ask for.
Anyone else actually tracking the timing between the animal reaction and the object movement? Would be interesting to compare notes across different locations.
