I don't understand how those two examples are different. Are you saying that the words can be used interchangeably?
As near as I can tell, yes, they are interchangeable. For some reason, "awoken" just sounds off to me, like it's maybe archaic. If I hit it as a reader, that's what I would think. So maybe if your story is trying to convey something from a past era, or the like, it would work. If you're dealing with a modern setting, I'd go with "awakened".
But, in either case, it pretty much dictates a passive sentence construction, and you might avoid the question by recasting the sentence into an active construction.
Addendum: I posted this before I saw your last post, so it's a little irrelevant to that purpose. But as a general writing comment, maybe useful, so I'll leave it as is.
