    ChatGPT:

    1. People blind since birth

    They usually do not see images in dreams, because the brain never learned how to process visual information.
    Instead, their dreams are built from other senses:
    • Sound 🎧
    • Touch ✋
    • Smell 👃
    • Taste 👅
    • Emotions and movement
    So their dreams can feel very vivid, but they are non-visual experiences.

    2. People who became blind later in life

    If someone had vision earlier and later lost it, they often still see images in dreams.
    This happens because the brain already has stored visual memories.
    • Some people keep seeing images in dreams for many years after losing sight.
    • Over time, the visual part may gradually reduce.

    Why this happens​

    Dreams are produced by the brain during REM sleep, where it recombines memories and sensory experiences. The brain uses whatever sensory information it has available.

    So:
    • Never seen → dreams use other senses
    • Seen before → dreams may still contain images
    If you're curious, there’s another interesting fact: people who are blind tend to have slightly more nightmares than sighted people, possibly because of increased stress from navigating the world without vision.

    That's not how it works Machan. Brain can only process the data it already has.
