Is there a specific word for the hallucinogic state one get's when feverish?

When I was a child, I once got those when in a serious febrile episode, caused by bacterial infection. I see that sometimes happens to children, but not adults.

My question is: is there a specific word for that?

In my language there's a specific name for delirium caused by fever, (at least elderly people around me had a name for that) so I wanted to know if there's such in English.

Apart from delirium, which is the obvious word that comes to mind, what alternatives might be there?

The closest we have is fever dream.

A usually frightening or unsettling dream caused by a fever; (in extended use) a heightened and often disconcerting vision, idea, etc.
