Where in finder are you trying to drag it from, & are you dragging it TO thee Dock next to Trash?
You cannot drag it from the sidebar, but open your home folder in the Finder, drag Documents on the right, to the right side of the Dock next to trash.

Instructions haven't helped. All I get is the curved arrow with instructions to open in the Finder. Going in circles. Also, I was only able to receive your instructions on my iPad, not on the MacBook Pro for some reason. JS

My grey line is about 3 mm wide.
You may find that it does not look like a folder when in the Dock. It may look like the first item inside the folder - if this is so change the Dock item from Stack to Folder by right clicking.
