Personally? If there was a Pluto transit, collectively, that I'm scared of, it's Pluto in Taurus. Taurus is the environment, currency, etc, etc.

Don't be shocked if Yellowstone explodes during Pluto in Taurus.

Personally, Pluto in Aries and Taurus scares me the most! Pluto in Aries, volcanoes?? Does Aries rule volcanoes? I don't know, someone needs to inform me.
