Unnaturally bright light coming from an old, remote dense forest in the middle of a night.We were in a summer cabin which is deep in the forest of the town of Sipoo Finland. We saw an unnaturally bright light about 300 meters from our cabin. The light came from a dense forest where there are no other cabins or roads of any kind. We couldn't know what it was because the forest was so dense that we couldn't use our old binoculars. We were too frightened to go and see for ourselves. It was there for about ten minutes. We wen't inside to get our brand new binoculars but by the time we got back to the yard, the light phenomenon was gone. The next day we wen't to the site and we came to a conclusion that there could not have been anything reasonable because the forest was so dense and there were no roads there! We were also the only residents by that time for about 4 kilometer radius! All the other residents were elderly folk who wouldn't wander out on such a late hour.
