I spent quite a while on my only visit to Clava Cairns near Inverness in 2001 photographing and filming it all, and then dowsing the NE and central area of the site. Just before I left there was no-one around, so I bent down and placed my right hand on a small crystal I'd noticed, below halfway down, on the NE face of the large oblong standing stone near the NE cairn and its circle. I closed my eyes and felt a strange dreamy sensation, also unlike anything I've ever experienced before or since!
(I'd earlier commented to another visitor there on the stone's similarity to those oblong slate slabs in 2001 - A Space Odyssey, and we'd laughed because it WAS actually 2001!)
Something is not right. This message is just to keep things from messing up down the road
