I'll explain: Delusions are when you think something is happening and it's not. For instance you may think you're the president of the United States, but you're not. That's a delusion (unless you're an african american senator from illinois). A hallucination is where you sense something that's not there. It can be something you think you smell or see for example that's not really there.

Delusions/Hallucinat: Delusions are false beliefs. Hallucinations are false perceptions.

Different : A delusion is something that can theoretically happen, but is not very likely. An example of this would be, when a patient tells me that Cindy Crawford is in love with him. That's a delusion. A hallucination is, by definition, any one or more of the five senses interpreting stimuli from the environment that does not in reality exist.

How can I tell if i'm having delusions or hallucinations?

Reality check: Delusions & hallucinations are considered "psychotic" symptoms. They represent impaired contact with reality. One way to check on your contact with reality is to take actions to be objective. This means that you could evaluate your beliefs and confirm your perceptions by asking trusted others if they agree with you. If your beliefs and perceptions are clearly false they'll say so.

Good question: A hallucination is a perception (seeing, hearing, feeling, even smelling) of something that is not actually present. A delusion is a belief in something that is not true despite being presented with logically undeniable evidence to the contrary. However, a belief that is very commonly held in a given culture is not considered to be a delusion even if it otherwise meets the definition.
