Sound is an illusion and we can communicate through our minds and yet our brains trick us into hearing something so we dont go insane. Everyone else can hear what we are thinking when we think we are speaking.
My friends heard my speak even though i was lip syncing so this proves this theory of The sound illusion.

The moment when you think you smell a fart, but nobody actually farted.
Your standing with a buddy and suddenly smell what you think is a fart so you say "Hey man, something smells like shit. Did you just blow ass?" And he says "Na man, you must be having a Craptical Illusion!"

According to Nietzsche’s psychoanalysis, freewill might only be just an illusion. A trick of the mind.

Animals and humans have genes that partially predetermine how they act. But it is really thoughts and beliefs that guide people.
Illusion of Free Will- like Buridan’s Ass which states that an Ass that is equally hungry and equally thirsty will both die of either starvation or thirst if water and food are kept at a same distance but in completely different directions if the Ass can only choose from two. Even if the ASS walks the same way to curb their thirst or hunger, it ends up dying of either thirst or hunger because it can only fulfill one need and not the other. Because the animal acts on instinct it is unable to make a rational decision and distinction and can only go to one option.

The moment when your brain starts to create flashes of light from your BlackBerry device, fooling you into thinking you have a text or BBM, when in reality, you have none, and are having withdrawal symptoms.

very common to the Phantom Vibrate,
Ben: Did my phone just flash?
Dave: No bro, it was just a BlackBerry Illusion, you really need to get out.

A person who does not exist. A sub-consious side of one being who lives on the Planet Earth who was once a person, but forgot who they were. Some may say this person had a life, but the sub-consious took over and now lives alone, friendless, and something someone would call dead inside.

One feeling of symptoms of Bipolar, but isn't classified as such disease or illness.

Who am I, I am A Twisted Illusion...

As I stand before myself, I try to understand who I am... Flashes of what seems like a life appear before me...

When the passengers of a car misjudge the speed of the vehicle because they are viewing the analog speedometer at an angle. When not viewed straight on, the needle appears to indicate higher or lower speeds than the vehicle is actually travelling.
Jen: Slow down or the cops are going to arrest you.
Bob: I'm going the speed limit...
Jen: It looks like you're going 5 over from the passenger seat.
Bob: That's the spedical illusion messing with you.
