Hallucination vs. Delusion
A hallucination and a delusion are similar events with different details.
In a hallucination (noun), there is a sensory experience of something that doesn't really exist for anyone else. This is often caused by various physical and mental disorders, or by reaction to toxic substances. Hallucinations will be visual or auditory experiences for the sufferer. People hallucinating often report seeing things that are not real or present to others.
1. "My dream last night felt like an actual hallucination. I was lost in Wonderland with Alice."
A delusion (noun) is a false belief, opinion, notion, or illusion that is resistant to reason or confrontation with actual fact.
1. "My classmate is under the delusion that he is actually Napoleon Bonaparte. No one can convince him otherwise."
Hallucination and delusion can be used in a sentence together. Let's take a look:
"If you're deluded enough to believe that Rebecca's hallucinations are real, then maybe you're not in reality either; it is obvious that she is pretending to see things."
