I had a friend in nz whos patents house had an old maori pa on their land. Nobody told me and when a group of us went for a walk they went up to show us the site. I have rearly been that uncomfortable. The unwelcome vibes were soooo strong that a few of us ran back to the house. After everbody was back they told us what the place was.
When they built the house they had to get contractors from a different place cause no locals would work on the property. But, his parents never felt uncomfortable or odd. Terror is too strong but not by much.

Sorry if it doesn't make sense, the barefoot princess is covering me with kisses
