I don't know...interesting question!
Animals do sense when something strange is going on.
Was there anything happening at the moment when your betta freaked out, like a loud noise or anything with his home?
I do remember when I first go Thai (my VT male), he got scared of a thunderstorm that came by here. The first thing he did when it thundered was burry his face inside of the plant in his tank. (poor little fishy!)
He did that twice and then got used to it, so he isn't really scared by them anymore. At least I haven't seen him do that, if he is afraid of them he hides.
