The first time i visited callanish at night i felt really welcome ,the next night when i walked up i felt the stones were a group of people talking about me and i wasn't welcome, i went in anyway and it felt horrible i ran to the van (all the days were normal), on the 3rd night i went back not knowing what to expect but put it like this i felt like i was been hugged all night so it's safe to say it was all right.
