You can say "You're delirious" - but it doesn't mean the exact same thing as To hallucinate. Hallucination comes from drugs, hypothermia, dehydration etc..You think things which are not really there.
To be delirious means you are "blinded" by excitement, like the Italians were on Sunday
👁 Wink ;) However, it could mean that you are seeing things which are not there.
