They can: Particularly if the fever is quite high or the person with the fever has a coexisting compromise of the brain like any of the forms of dementia. Remember though, it's not that common for healthy adults with a fever to hallucinate and may suggest a primary infection involving the brain or connective tissue around the brain.
