The elements that cause panic in dreams can vary from person to person, but the following are generally considered to trigger a universal panic response: 1. **Chasing or being chased**: Being chased by an unknown or scary entity can often cause a great deal of panic. 2. **Falling**: The feeling of falling suddenly from a height can easily cause panic. 3. **Disorientation**: Getting lost in an unfamiliar or complex environment can cause people to feel panic and helpless. 4. **Immobility**: Being unable to move or shout in the face of a threat in a dream can often be extremely terrifying. 5. **Loss of a loved one**: Dreams about a loved one being injured, missing, or dead can trigger deep fears. 6. **Paranormal**: Encounters with supernatural things, such as ghosts or unknown entities, can cause panic. 7. **Natural disasters**: Disaster scenes such as earthquakes, tornadoes, or tsunamis can also trigger panic. 8. **Body deformation or injury**: Becoming deformed or suddenly suffering serious injuries can often cause people to panic. 9. Loss of control: For example, uncontrollable vehicles or rapidly changing environments can also trigger tension and panic. Importantly, dreams are very personal, and people with different backgrounds and experiences may react more strongly to different elements. Therefore, these factors may be more likely to trigger panic reactions in some people. When designing these elements, you need to be especially careful to avoid causing unnecessary psychological stress to yourself or others.
