When butterflies attack...

I've been laid up in bed basically for the last week, and I stopped taking happy pills yesterday (that's what I call my Oxycontin). Which apparently makes the happiness stop.

I just woke up-- quite forcibly-- from a dream I was having. I was in San Francisco (of course) with some of my friends and we had been walking along a city area to then settle down in a park. And there are butterflies in the park.

And they attacked me! In the dream, of course. But they attacked my face in the dream! What could that possibly mean, metaphorically?? Someone help me out... because now I have a certain uneasiness when it comes to butterflies.
