  Hi Zeddy!
  Great question! I had never heard of this before so I did a bit of investigating and found out that a group of scientists in Denmark have reported that 25% of blind people have nightmares compared to only 7% of people who can see! They think that it’s because we have nightmares to adapt to things in the environment which are a threat to us and blind people are more at risk of outside threats than people with normal vision. You’ve helped me learn something new today so thank you! 🙂
