Can you bring people back to life?

If you're playing on pc there's a console command to spawn another one but if you're not then its impossible without using the dead thrall spell

Before you resurect her as a dead thrall, make sure you put Daedric armor and weapons in her inventory so she is equipped with good armour and weapons while she has been ressurrected.

I did this with uthgerd the unbroken. Played the song "resurrected" while.i played with her alive then lol.

That song is a wrestlers theme so if you want to look it up on youtube, type in:
Jeff Hardy theme song Resurrected
