Can you elaborate on that idea, please?

It's basically a reiteration of the views expressed by crop circle researches like Rob Buckle and Matthew Williams.
On the one hand almost all crop circles have "combing" marks easily visible from the air, which is a dead giveaway that the crop has been flattened by boards. And so it would seem a unavoidable conclusion that crop circles are made by people.
On the other hand there are several accounts of odd occurences associated with the crop circle phenomena, although the evidence for this is somewhat weaker and on the whole mainly anecdotal.
One of the strange phenomena associated with crop circles relates to the timing of their appearance and the choice of design and location. There are several accounts of people meditating or praying for a certain design only to discover the very next day that the design that they were meditating on has appeared during the night.
For instance crop circle researcher Colin Andrews has an account of this happening to him. And Matthew Williams tells a story of him being involved in a similar incident as a member of the team actually making the crop circle; only learning afterwards that a group had been meditating on the very same (allegedly) design.
There are also accounts of two different teams unbeknownst to eachother going into adjacent fields on the same night and making very similar designs. John Lundberg tells a story like that.
If these accounts are true and if they cannot be ascribed to mere coincidence, they point towards some type of synchronicity or telepathy. Or perhaps even to another intelligence behind the crop circle phenomena, which is the view Matthew Williams subscribes to.
And then it gets even stranger.
Apparently many circle makers have experienced strange happenings in the field when they are making the circles. These reports include hearing strange sounds, seeing shadowy figures or balls of light behaving intelligently and interacting with the team - in some instances exhibiting hostile behaviour. In a few cases the teams got so scared that they abandoned the circle and fled the field. In these cases the evidence is very slim consisting only of photos of the unfinished circles and the accounts by the team members, so I suppose it can't be ruled out that it is some sort of prank played by (or on) the team.
In summation: Crop circles are made by people. But if any of the unusual accounts above are true there still is a paranormal aspect to the phenomena.
