I kind of understand that Irene is able to take over someone's body like that, since i'd assume she practices a lot trying to enter her own daughter's body so she dont need to be a dragon slayer anymore. But Wendy capable of doing that too that's where I feel "HOW did you know how to do this?" because Wendy had no reason to learn that magic or should know it.

The only thing MAY explain is that because that because its an empty shell like you said, it is easier to enchant into it...
