Between your ears you have an amazing piece of hardware. The human brain is the most complex structure ever found, at least according to human brains. There are over a hundred billion neurons stuffed in there with trillions of crisscrossing connections.
Even our best efforts to recreate it electronically can only make small aspects of what the brain can do like playing a game of Go or saying crazy stuff on Twitter. But there is a price for all that complexity. It means that are a lot of ways for things to go wrong like hallucinations.
Schizophrenia:
Ideally your brain is taking information from your sensory organs, your eyes, ears, nose, tongue and skin to create a complete picture but sometimes your brain skips all that and starts playing tricks on you. Ever thought you heard your name being called when you were all alone? Hearing voices is actually the most common hallucination. This is especially true for people with schizophrenia which is thought to be partially caused by chemical imbalances in the thalamus. That’s the part of your brain used to coordinate different sections to work together. To a schizophrenic these voices sound as real as if someone was in the room talking to them and they usually comment on what the person is doing or thinking oftentimes they are mean and negative. It’s not very pleasant. Brain malfunctions can also cause you to see things that aren’t there like faces with huge teeth and eyes of a certain part of the Fusiform Gyrus is overactive.
Epilepsy, tumors or migraines can cause Alice IN Wonderland syndrome where people see the world tiny or gigantic. Migraines can also cause similar hallucinations like floating jagan patterns.
Routine:
Sometimes hallucinations are caused when your senses are not working properly. People who have gone blindly experience Charles Bonnet Syndrome and see whole scenes play out in front of them though they don’t feel like they are a part of it instead it’s like watching a boring movie. Elderly people who are hard of hearing sometimes hear music s clearly they are sure it’s those neighbors with their pop music and stereos.
You can still hallucination even with the healthy brain and working senses. They can happen when you are not feeling your best from lack of sleep, hunger or fever. Grieving people often still see, hear and feel the presence of their loss of loved ones and of course some people choose to alter their brain chemistry intentionally with drugs that can cause hallucinations.
Certain drugs like LSD are currently being tested for positive effects on certain conditions.
