Within the various dust-occultation ideas, there is some quantity of dust required to create the one deepest dip of 20%: Boyajian and Thompson calculate that the comet family scenario requires 648,000 giant-comets (each with 200 km diameter) to create the century-long fading, all orchestrated to pass in front of the star within the last century — this can be compared to the entire mass of the Kuiper Belt in our own Solar System.
I do not see how it is possible for something like 648,000 giant-comets to exist around one star, nor to have their orbits orchestrated so as to all pass in front of the star within the last century.

So I take this century-long dimming as a strong argument against the comet-family hypothesis to explain the Kepler dips.
So what is going on with this star? We don’t know, we still scratching our heads, I think. It’s a mystery, but an amazing one.
The aliens idea may make this seem silly, but the data are real. Something is going on around KIC 8462852 star. I don’t know what it might be, but what I can guarantee is that when we do figure it out, it’ll be something pretty amazing.
