A Skyrim question for those in the know...or willing to test this

I was talking to another Skyrim player today, who asked if I had ever resurrected/re-animated a dragon.

No, I couldn't even imagine how such might be possible...right? You kill it, you take its soul immediately, no oppo to resurrect.

No, he says, there's a gap between the death and the soul capture where you might resurrect it. If your spell (and I guess your appropriate magic skill) is high enough, you can, he says.

I have not tried this? Any matching experience on this?

You do reach a point where you get to summon a dragon (Durnhevir or something like that). I haven't found it that useful.
