Amazing footage has emerged of a forest carpet appearing to breathe like a sleeping giant.
The video was captured by Brian Nuttall at Apple River in Nova Scotia, Canada, on his mobile phone.
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.
"The punishing prevailing winds have taken their toll on the side hill, the roots have loosened and the mossy ground from the once shaded forest floor are giving way, soon to be toppled over."
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.
