2-3 Cylindrical (like a hockey puck in width) objects suspended 100ish feet above the ground. Bright round lights.

Sighted by me and my mother. The objects were complexly still. They were massive... suspended over the hill parallel and east of I-5. We could see them to our right driving south (also parallel to I-5) on Hwy 167 S. Each one seemed to be larger than several neighborhood blocks...but memory not as clear on exact size now and the hillside was a number of miles away, so real sense of scale is likely skewed.
Thay had large round lights evenly spaced around the object. While extremely bright, the lights also did not seem to be shining on anything or lighting up anything in particular.
We saw them, talked about seeing them, talked about stopping to look at them. But for some reason, my mother did not stop. She just drove home and we went to bed. My mother says it was as though she lost time. For me it felt like we were compelled to go home...were not allowed to stop or look. Neither of us can recall why we didn't stop and look...even though we talked about it.
We both remember this event. And have never been able to explain it.
