And so it starts with that sense of you're watching the partial eclipse.

It's really interesting, but there is a moment that you notice that something's going a little bit wrong--that sense of wrongness.

So the light doesn't quite look the same as what it normally does.

Everything's just a bit weird.

There's this darkening in the sky.

The wind kind of picks up or changes direction.

And then you're really starting to think this is not how the world is, and you really start to pay attention.

And then moments before totality, if you're in that path of totality, moments before you get this ominous feeling that something's huge is coming and, you know it's the moon's shadow.

And even though you know it's coming, it really just is so unexpected.

Eclipse chasers actually used the [phrase] primitive fear.
