delirious

Being in the state of delirium.

[…]the angelic form of a creature whose very existence was a gigantic balm of Gilead to the lacerated body of our hero, and, in a half delirious state of mind, he felt like leaping mountains to raise prostrate female forms, and to become blessed with hymeneal joys of the most glorious character; but, his imagination soon forsook him, and a raging fever, accompanied by the most violent deadly delirium, ensued, which lasted a fortnight.

Having uncontrolled excitement; ecstatic.
