The ET aspect has never interested me until recently. Actually through the Nag Hammadi codices I caught glimpses of what appeared to be descriptions of ETs.
Since then I have read some material on the subject as it seems to intertwine in our future.
Reading Dr. Karla Turner´s book was indeed informative. She devoted herself to the subject since she and members of her family were also being abducted. She worked with a regression therapist who specialized in going deep, beyond screen memories. Many people described being told that they were chosen to bring forth information to the populous at the right time and so forth. Beyond the screen memory things were very different indeed. Physical experimentation of a cruel, non-compassionate type was apparently being performed; souls removed from the "body suit" and more.
There was also a doctor from Harvard who wrote a book about clients who came to him with similar issues. The feeling at the end of the book was similar to what Karla was bringing forth.

This is complicated; search for the truth inside yourself does in fact seem like sound advice.
