Owlfly

When I took these pictures, this insect was in a dark area and I thought it was a dragonfly. So, I used flash to take a couple photos, and didn't pay much attention to it because, you know, I have a lot of pics of dragonflies and damselflies. But today, looking at the photos, I noticed that the proportions of the body seemed a little odd (mostly the eyes, that look too small), and, above all: have anybody seen a dragonfly with antennas like those ones?
