What are the difference between illusion, hallucinations, and delusions??
In: Other
Illusions are usually trick of the brain. Your brain seeing things and interpreting them badly, or seeing something that is not entirely true. Either the brain fucking up, or other things playing trick on us.
Example are seeing face in things that don’t have them. It’s an illusion our brain play on us usually when we see three holes aligned for eyes and mouth. It leaves a strange feeling of being watched. It’s not a face, it’s not drawn to be one, but our brains makes us believe it is. Same for mirages in the desert, but for the other half. We see something but that something is not entirely true, there is an oasis but it’s not where we see it. The thing we see aren’t fake, they’re just not as we expect them.
Hallucinations is slightly different. It’s when something doesn’t exist, and our brain entirely create it. There is usually little to no basis for them, and it’s entirely our brain tricking us into believing something that doesn’t exist is there.
Example are seeing ghosts, or people tripping on drugs that see pink elephants. These are not real, have no basis on reality, yet our brain for one reason or another sees them.
Delusions are completely different. They’re not tricks on perception, but tricks in belief. A delusion basically mean that someone believe something that is false and simply refuse to see anything contradicting it. They’re usually fixed belief that one simply cannot easily drop. These are really dangerous and are either self manufactured or someone manufactured them and planted them in you to control you.
Some may say that religions or flat earth could be considered delusions in that regard. I’ll let you decide for yourself. More concrete example I can give are people that strongly believe that a star or otherwise important person that they’ve never met and may only have crossed eyes with once truly loves them. This one is usually self created and simply prevent you from seeing the truth that they most likely just looked at the crowd of people you were in. Another example are sects. They usually prey on you at a moment you’re emotionally weak and will simply sell you a delusion that will make reality easier to cope with. Like the idea that you feel sad because you own things and should give them to the sect so you’ll be liberated. The usual sects example are most often selling a delusion and most of their effort are to reinforce them to make sure you don’t break free.
TL:DR: Illusion is when you see something wrong. Hallucination is when you see something that don’t exist. Delusion is when you believe something wrong to a point it’s unhealthy.
