Nice, what a beautiful experience. This happened to me when I was about 18, in the exact same way almost. I barely remember once I got out of the earth area though. All I remember is being placed "back" in my body, it was also a very peaceful journey.
Interesting a reptilian being appeared in front of you. They can do that lol. I'm not sure how I would handle that lol..I have seen them in more than one way, but flesh and blood in front of me- only in abduction (lol jk..or am I)
I will discuss these ideas now. Archetypes, and beings bein representative of them do not necessarily mean that they do not exist also in a physical way. For example, yes some of the "Draconian" beings are directly connected to the Saurian and Dinosaur like beings- in fact some claim they were a "creation of them." The purpose being, to place an archetype of themselves within humanities "living library" of organisms and expressed life. It's like putting a "piece of themselves" into our planet, for the purpose of having a direct connection. Mind on Mind as you say, from long distance away.
As I understand it, from insiders- mind on mind is the most common form of communication. And they do so with human beings (and I'm being told, many of them do so with me, and wish to do so with me more) on a frequent basis believe it or not. It's a developed kind of skill, and the beings themselves develop a network (organic or artificial) which overtimes becomes solidifed into an "energy grid" which can be accessed at any time. The Tibetans call it the "ontah." Some guys in top clearance programs who deal with the beings from elsewhere have this skill as pre-requesite to their work (many of them, are also physicists, as they are all psi operators, RV, and also Occult afficionados). Same within some sections of the famed "Illuminati."
ET's for the most part, are not hostile. They most certainly do have agendas though. There is a bigger game/drama out there then we are aware of .Some of the peeps I've talked to categorize them into a few categories.
-Organic (biological like us, which don't seem to be very many).
-Artificial and Android, that is- they can appear fleshly but when observed from the inside have an artificial interface, organs, and innards. Run by AI.
-Energetic- beings who can be accessed with extended human function, astral projection, Remote Viewing, telepathy but do not have physical, or biological bodies like us. (And yes this includes extra dimensionals as well)
-And yes, the fabled "Ultra Terrestials" who are not bound by any sort of material kind of body or anything whatsoever. They are from a different level of manifestation who can appear however they want.
The "techinical" search is the biggest nonsense in the world. They came come and go with ease. Most craft are not even nuts and bolts real. They are organic, living beings within themselves that are often sentient with the beings who reside in them. In fact, as I understand, because of our limited conception of reality, an entire being can be the craft AND its crew. A higher dimensional being. When we make "contact" with the being, our mind translates it into a holographic (3d) medium from which we can "understand." That is, we are looking at a crew of beings inside of a craft that appears to have no real nuts, bolts, or technology as we know it, but is more "instant" and tuned into the mind and emotions. We are looking at the Whole of a being in separate parts.
SETI and all that stuff is garbage nonsense created by the Gov to coverup what they already know. Communication isn't done via radiowaves or any other kind of rudimentary technology (LOL).
Also, what are we as an archetype? Humans? Are we bacteria too LOL. Look at the way we treat our planet. Are we "rats in a maze?" Many of them look at us that way. What is a human being to a flesh eating reptilian being? Maybe how we see the "cow archetype" in the west (aka, a big juicy meal). Also, archetypes vary on context. This is why I don't use hindu symbols when I meditate, because I did not grow up in a culture where a cow is "holy." My subconscious sees them as "slabs of meat." My personal opinion is if archetypes exist, at a local, or universal level- then they have EXPRESSIONS or manifestations of the archetype. For what is the manifest reality in front of us but archetypes within the collective unconscious of mankind?
