Hallucinations Explained
When someone like Carlos is hallucinating, he experiences perceptions or sensations that do not exist in reality. These can affect all senses but are most commonly visual or auditory. For example:
- Carlos might see a dragon flying in his living room, although there is nothing there.
- He could hear music playing as if there's a concert next door, but in reality, it is silent.
- Carlos might feel bugs crawling on his skin when there are none.
Such experiences are not based on external stimuli but are generated by the brain. Various factors like mind-altering substances, chemical imbalances in the brain, or psychological conditions can cause hallucinations.
