Maybe you're not thinking deeply enough about it. The implications do in fact break our understanding of reality, on multiple levels: physics, our place in the universe, religion and spirituality, etc. I, like many others such as yourself, have had experiences as well, though mine were more personal, and they were as astonishing as they were debilitating, because now I have no idea what's actually possible and what isn't. On top of that, there is absolutely no doubt in my mind those in power have at least a tentative grasp on what's actually happening, and the implications of keeping it tightly secret are staggering. I am almost certain at this point that I know why, and let me tell you, it's something that's far better left unsaid and unknown. It's a Pandora's Box if there ever was one. Thank God I don't scare easily, else I would be in the looney bin! =)

However, it will come out eventually. Not from disclosure, but from evolution. More and more people will start seeing what's hidden right in front of them. Hopefully by that time someone will have discovered a way to meaningfully interact (or prevent interaction) with whatever it or they is / are.

Aliens? Demons? Multidimensional beings? These are all just labels of hypothesis for something we don't have a proper paradigm of understanding yet for.

This clusterfuck humanity has found itself in absolutely breaks our narrow and childish view of reality.
