A subject-orientated secondary predicate [according to some grammarians] (arguably depictive, arguably resultative) is probably what you're seeking. But
- She returned from her spiritual retreat alive
doesn't work for two reasons, the first being that the default sense of 'alive' is 'not dead' here, as remarked by Peter.
But the fact that
- He appeared at last out of the jungle[,] alive
sounds far less natural than
- He appeared at last out of the jungle, alive and kicking
shows that not all such constructions work equally well.
- She returned from her spiritual retreat vivacious
doesn't sound at all natural, whereas
- She returned from her spiritual retreat refreshed and revitalised
sounds fine.
- She returned from her spiritual retreat full of vim and vigour
is equally idiomatic, slightly less formal.
