OK so this from the last employment site. One of our Radwaste techs was Chief Joseph's great grandson(Nez Perce), Terry, nice guy defined as Native American by appearance, has since left this Earth from lung Cancer(Smoked a pack and half a day EVERY Day for seeming ever) since he was 10.
Anyhow I had a event on the Night Shift in Radwaste, was changing the turbine building drains discharge filters("Clean" water) when I saw a shadow move down the filter row aisle about 45 feet away. The aisleway has doors to valve and equipment rooms that be design were nasty hot either by the liquid flow heat or from Nuke Zoomies HOWEVER were kept open to minimize the need to open them as were missile shield doors(Solid 2" steel and had little effect on rad levels. It was on the furthest door I saw said shadow move.
Finished my filter swap and placed back online then went looking for the Funny Fkr that was trying to stir me up. Nobody around, only two stairways and both visible from the filter skid so no one came up or left. Looked for lamp glare or a bad Sodium lamp bulb(tend to swim and flicker, NADA so went back to duties, cleaned up filters area and trash and saw that shadow move on that damn door again, walked down the aisle, NO WAY SHAPE OF FORM was there any lamps that could cast a shadow from any component in that area and that particular valve room the lamps were all burnt out. Mentioned to Terry, he stated FLATLY that while he was there during construct of the plant excavation workers had found a Indian Burial site, right where the RW Building was to be situated, so on the quiet all the materials were moved to a debris site and covered up(Still there as he knew), he had similar events as a NON Hostile spirit roamed the building halls, caused shadows, lights would fail(not bulb failures) or bangs or clicks from rooms with no machinery in them.
Saw that shadow one other time, and after never again before retired.
