If we could talk to the aliens, just imagine it -
Chatting to a gray in grayanzee
Imagine talking to an orion or chatting to a reptaloid
What a neat achievement that would be.

Okay, as far as communication with aliens go, there are, in my experience, two different ways. Both ways employ the aliens advanced technology with the ability to tap directly into the human brain.  Now I know the mere idea of someone or something fiddling around in what is universally considered  one of your most private and precious bodily organs can evoke somewhat of a negative reaction. But for all intense purposes this direct access is the quickest and most efficient way to talk to someone that has an entirely different language, almost instantly. 

 One of the ways which the grays employ this technology is simply by talking to us, in english, directly into our heads. The grays seemed to have mastered the basic english language quite well and will communicate in real words which, if your eyes were closed, you would swear someone was speaking out loud. As a matter of fact the first time I communicated with a gray, there were three of them in the room and I looked back and forth at each one trying to figure out which one was talking. Eventually I realized I was "hearing " the words in my head. It does take a little getting used to.

 When I say that the grays have mastered the "basic" english language it is because, although they will communicate and even answer some questions, they are not really very "chatty." In my experience, if you ask a gray a question,you will get very short very concise answer. I dont know if this is on purpose to keep all communications with humans to a minimum or if they just dont have the understanding of all the nuances of our language to carry on  longer conversations. In any case a gray definitely would not be someone you'd want to stay up and talk to all night.

 Another way in which the aliens will communicate is through a visual image. I believe they use imagery, again placed directly into the brain,  when they dont want their presence to be known or perhaps just to keep nosy humans away.. For instance, I once walked up upon an alien collecting plant samples along the Susquehanna river. I was at first startled but when i realized the alien had not noticed me I slowly walked forward. As I got closer to the alien there was suddenly an image of a snarling wolf with enormous teeth planted directly in my head. I believe I had crossed into a "go away" zone around the alien and this was their way of letting me know it. I have also received an image from a gray as an answer to a question, the image was remarkable to say the least and I did not understand it for many years.
