Glimpses of a parallel reality?!

First of all, I'm a skeptic and mostly someone who doesn't think of the supernatural or the notion of parallel realities as authentic. I think that UFOs, ghosts, and other various phenomena are explainable, at least about 90 percent of them. And there are probably many things, or scenarios, that once can think of which are highly strange. When I was much younger, I had what I'd describe as "glimpses of parallel realities"; that's about how inexplicable my life would become at times. At their height, my emotions and/or inner feelings were so strong, so unexplainable, and so indescribable, that I was just about convinced that there was something more than special, a supernatural aspect, to our universe! And to this day, I think that I was lucky enough to experience something truly deep; what I like to describe as "parallel realities". But don't think that I necessarily think of such a notion or idea as real. I just use the term "parallel realities" because it's the only term that I can think of at the moment of this writing, even though it might be even stranger than that. If thoughts, emotions, or feelings were like entities, then I'd describe meeting the fourth kind! So what are these "extra dimensional" emotions that I experienced back in the day, when life was acceptable and feelings actually felt good? What exactly was going on?! At the climaxes of life, I felt something just like euphoria, except that it was inexplicable and much more intense than euphoria itself. It's as though I was experiencing another spatial dimension using my sixth sense itself, and in that fourth dimension, the universe was changing with an expansion so ethereal that one can only think, and not know, what this was. I want to know if anyone has any further information about these types of experiences, maybe they are not just phsychological or mental, but might have a deep connection to the universe. If you have any further information, please leave a comment. I think that it may have to do with the fact that something, maybe my intuition, might have been telling me that these current times bring indescribable elation along with them, and don't stray away; unfortunately, I have no ability anymore to access these emotions, not even once, for any amount of time. As a result, I've been in despair which quickly has turned into perpetual anguish inside of me. And every moment of my life that goes by, I can tell that I'm only striving further away from what is great and acceptable, the life that perhaps might have been had life not deviated away from the norm.
