I have had many thoughts about Triangle, Cigar, Spherical and other types of "ufo" and a lot of them made my head hurt, but, I have a few for you to ponder on if you so wish.
As with all such phenomena you must first exclude all that it is not. Which is not quite as easy as it sounds as the primary source of reporting is always based upon an individuals perception ie what you may perceive as a triangular ufo I may perceive as a delta winged aircraft depending on how the light hits it. You must also be aware of the information you have in your mind as to how such things are perceived. To get an idea of what I am saying here is to look at the evolution of aliens & alien craft throughout recorded time. The Reptiles & Greys & whatever else were once called Angels and Demons, Metallic saucer shaped craft were once Chariots of the Gods. As we progress technologically so we attach those labels to what are beings that have been in existence as long as the universe has.
Now to the actual reality of such mysterious craft and as to why they appear "see through". I will state here that photographic or video evidence is subject to perception and does not reproduce what is actually seen, I will attempt to clarify this later.
To begin, I hope you understand that all "dimensions" or "realms" exist in exactly the same space time as we do, the reason why most are not aware of them has to do with the conditioning of the childs mind, but that is a whole different topic, essentially the liberated or free mind has the ability to discern them. Now some but not all of these dimensions are occupied by what are best called entities which when seen are unlike anything in our visual experience so are described by how the subject perceives them ie as a demon or as a reptillian or even, for the religious types, an angel etc. The same aplies to the so called craft associated with these entities. It is important to understand that a lot of what is seen and proven to be unknown are glimpses of "transdimensional" or "soul" ships, these are energy based and can only be interpreted by the mind according to what it knows, which in this day and age is what the media puts in your head. This also applies when the mind tries to interpret what cameras have recorded as in SmokeNmirrors pic, although it may have caught the whole craft the mind can only perceive a part or parts of it hence the observed morphing ability.
Right I am running out of steam thanks to that last spliff and if I don't stop now I will waffle on and on as I lose more n more of the plot
So I guess at the end of the day one has to forget all one thinks one believes about them and open the mind to see them as they really are, and yes they are real.
Wondering if this was a bit to heavy
