The patient was having hallucinations because of the lack of sleep.

delirio

Use 'delirio' for a sustained, often rambling, false belief or mental state, typically caused by high fever, illness, or intoxication.
A person lying in bed with a feverish expression, seeing floating colorful swirls and bubbles in the air.

It's a Masculine Noun

Always use 'el' or 'un' with this word. For example: 'el delirio' or 'un delirio'.

Abstract Concept

This word usually refers to the state of mind rather than a single specific thought, though it can be used for both.

Confusion with 'Delirious'

Mistake:Estoy delirio.

Correction: Estoy delirando (I am raving) or 'Tengo delirio' (I have delirium). 'Delirio' is the thing, not the description of the person.

Distinguishing 'ilusión' from mental states

The most common mistake is using 'ilusión' for a mental delusion. Remember, 'ilusión' in Spanish usually refers to a trick or a false appearance, like an optical illusion, not a persistent false belief or hallucination.
