Yeah I have been hypnotized and drugged too, and the lights they use effect the mind as well.  I kind of miss the worms but there is nothing fun about being visited by the Zeta's they just experiment on you and they communicate without using words, they can put images in your head and can communicate via thoughts, if I remember correctly.  The worms can communicate verbally and they have emotions and are similar to the worms in the men in black movies.  They were not as traumatizing to encounter.  I don't have any memories of the EMETHER at the moment, but if any come back I will share them.  Perhaps there ability to erase my mind is better than the others, or I have simply never encountered them.  I am glad I can use those videos to show the difference between a Zeta and a EMETHER, they are not the same alien, but can be confused because they both have large heads and eyes.
