It had me wondering if blind people actually dream about something.
Turn's out they do. But there are variations about that since there are some people who were born blind while there are some who eventually went blind as they grow up either by some medical condition or accident.
People born blind don't see in their dreams as they have no idea which is which. Instead, they experience a dream through taste, smell, sound, and touch. On the other hand, people who went blind later in their life experience their dream through touch, based on research.
What do they dream about?
Blind people often dream about their guide dogs and eating food.
Nightmares
Experts believe that blind people experience more nightmares than normal people do. This is because they face more threatening experiences that normal people do.
