"When she was brought into the room, she said, the humans introduced me to a female alien wearing a white plastic mask so that her appearance would not frighten the others and so they wouldn't focus on her eyes. Even though she wore a mask, I could see her eyes through the holes in the mask. They were big, black eyes. From that point on, I remember being right next to her, and her face stayed very close to my face...very intense."

The late Turner describes what she names Virtual Reality Scenarios in this book. If VRS are indeed occurring, which I believe is the case, then the abductee's brain would still be "awakened" during the night and the effects would be the same as if a physical abduction was occurring. A recommended reading.
