Watch the mossy ground of a forest rise and fall under the feet of a walker who captured the phenomenon on his mobile phone
Amazing footage has emerged of a forest carpet appearing to breathe like a sleeping giant.
It shows the ground rising and falling.
What in fact is happening is explained by Mr Nuttall in a Facebook post.
"I believe the larger trees are doomed to blow down but are currently spared, the smaller trees around them help hold each other up, as the wind pushes the trees into one another," he said.
Shot by Mr Nuttall on October 31, the video has been viewed more than three million times online and his Facebook post has been liked by more than 13,500 people with over 100 comments.
One person describes it as "creepy and scary", while others refer to it as "Mother Earth breathing" and a "floating forest".
