Abduction of my grandmother and great aunt

My grandmother was 13 and her sister 11, they were out in a Feild outside of their tiny village when the noticed a bright light approaching them. The light stopped over head low in the sky about 100feet off the ground. My grandmother said they were hit with the light and woke up an instant after. Terrified the ran home where they found that the village had been searching for them and that they had been missing for hours. My grandmother and great aunt would have reoccurring dreams of laying on an operating table with tall big headed humanoid creatures preforming different medical procedures on them. She described big oval heads large black eyes and small mouths. She had the nightmares untill the day she died. My aunt also had the same dreams up until the day she died (God rest their souls) when she would tell us the story it was always a hassle to get her to open up about it, she always cried and always got to a state of panic and would stop.
