Dreams Are Subjective Experiences
- We study dreams through dream reports, not the dreams themselves, making them inherently subjective and private.
- This challenge is similar to studying other private experiences, like pain, relying on self-reports and descriptions.
Dreams Lack Universal Definition
- There is no universal definition of dreams; some see them as narrative experiences, others as any mental activity during sleep.
- Dreams vary from brief images to immersive stories depending on stage and definition.
Brain Regions Shape Dream Features
- Different brain areas activate during vivid dreams, such as secondary visual cortex and limbic system, explaining visuals and emotions.
- Prefrontal cortex deactivation explains lack of critical thinking in dreams.
