Is there a difference between an illusion and a hallucination?

An illusion is a "trick" that may be perceived by many.
A hallucination is personal.

It is an illusion that the sun and moon are the same size.

It is a hallucination when the moon cracks open and a monster comes out and eats the big city on the horizon.

One of my most favorite (personal) illusions - not hallucination, because I know what was going on:
One fine sunny, summer day, the car was parked in the driveway under a tree.
When I looked at the windshield, I could see Cerberus - the three-headed devil dog - sitting in the drivers seat ... well, mainly all I could see were his heads - and they looked like they were barking (but there was no sound)

Really it was the sunlight filtered through the moving leaves of the trees reflecting off of the windshield.

Hallucinations are brought on by something more invasive.

A person can experience an illusion by forced perspective or word-play or some other mechanism which is pretty much limited to that one event.

Hallucinations don't have the same apparent apparatus. It could be chemically induced or fatigue or anxiety or illness even transient time or location based. But more difficult control or duplicate.

My favorite analogy is: it's the difference between the chicken and the pig; the chicken offers up eggs for breakfast don't matter if you like fried or scrambled. That's a sacrifice (think how you would feel offering up your babies to another species for food!). The pig commits at a whole nother level: he lays down and offers up all his body for bacon--that's baby Jesus in the manger at Christmastime!

Actually, I don't know if that's a great analogy to demonstrate the difference between Dodge and Chevy but I think you get the idea.

These are not really spinning - you can print it out and it will still look like they are spinning - but only the ones you are not looking at directly

@chaski Said

I can look at them and make them spin or not spin... together or individually.

I'm not sure why I can do this.

It might be good or bad thing.... but if bad, I promise that it doesn't involve violent behaviors...

An illusion is a visual deception
An Hallucination is a chemically released audio/visual program usually only occurring during sleep when dreaming, it is the toxin that carries the actual dream or night show.
Illusions can be easily broken by changing viewing location or playing with lighting
Hallucinations require more effort to recover from as they require the individual to take back control of their mind.
