What's interesting about some of the ETs that are described by these children is that they look like the creatures that supposedly were abducting Whitley Strieber. For those who have read Strieber's early accounts, you'll recall that the entities that were/are abducting him seemed not to be very hospitable and managed to give him nothing but nightmares. These kids, on the other hand, refer to them as mentors and friends. Moreover, Strieber doesn't appear to have been given anything that is validating of his experiences other than his word and a mysterious "implant" that some people believe is a fake. Other than that, he seems to be rather ordinary.
Another thing that's gripping about some of the children's accounts is their reports of seeing "dead" relatives on board the spacecraft where they're taken for their sessions.
