Maybe it's the Perseids?
I dreamt last night that a large old dresser appeared suspended in the sky near my house filled with every sweater I no longer possess. "I loved that, it was from GAP's '03 fall collection, bought in Providence, RI. And this grey one was medium-sized, they said it would stretch, but the wool was too densely compacted; it never fit right. And this green one was the first sweater-vest I wore tucked it into my pants..." All warm, fuzzy nostalgia until the glowing red-eyed alien spiders hidden within revealed their large selves and attacked. Then it was guns at dawn and green-bloodied mayhem until I vanquished them all with my army of old-sweater wearing duplicates.
Again, I think it was the Perseids...
And for the record, I was also surfing a list of DHS 'indicator' terms that included DEA, FBI, Border Patrol, and many others:
