Is this correct English?

Yes, grammatically feasible, but not immediately clear without some explanation on your part. You might do better writing 'wishes (swaddled OR masked OR covered OR buried OR hidden OR any number of other 'covering' verbs....) in disbelief.' It sounds quasi-poetic then, at least...

"Wishing in disbelief" actually makes no sense at all in American English.

There's nothing grammatically impossible about either of them; either is correct English. But then 'John is 60 dollars tall' is perfectly grammatical, correct English, too - it just happens to be nonsense. You haven't given any context, so it's impossible to know what meaning you're trying to convey, and nobody here can tell you which (if either) successfully conveys your meaning.

Sounds right
