The other aliens' other weapons? Dinosaurs. Velociraptor-like things about as tall as I am and a lot longer. Primed to spring towards me and eat me. Lots of teeth between me and their gullets, and those teeth putting on an impressive display of snarling. Oh dear.
I jumped aside (must have had springy tentacles, or that handy floating thing Dominars use in Farscape), reached around the dinosaur's head, and started scratching. Suddenly MUCH more placid, submissive, happy dinosaur. Those teeth even seemed to be displayed in a grin. Suddenly a defused standoff, too. Phew. Crisis averted. Now I don't have to find out what it means when dinosaurs eat you in dreams. ;-)
Meanwhile, I'm staying home, including getting back into bed in a bit. Maybe there'll be more dreams!
