Is there a reincarnation thing?

Experience a vision of distant past is fascinating. Like stopping the car in traffic jam and, looking outside the window, find a new building in a place you thought you knew well. The realization you did not know the building was there "all that time" is already that feeling of surprise. Even more if it's features  would call your attention, but you never knew it was there. You are certain to be in the same city and street you pass everyday, but, suddenly the town has changed because you never saw that specific building. Recognize a past life is very similar to that. You know you are yourself , you recognize the surroundings and you know you are not in that time. If it's a spontaneous "trip", meaning you are experiencing such a surprise without being in trance or under influence, things are even more fascinating. 

I could be shaking hands with someone and start seeing vivid surroundings that were not the ones around us before touching that specific person. I could sense smell and feel temperatures that were not the same as those that looked like the real ones. Yes, real ones. Real world, Reality. That one you think is what it is, but is not. Because science already proved that reality is what your brain perceives as such and that all that can happen to you may be, indeed, be happening all at the same time but in different spaces, or timelines. My mind can't get all that but I do understand why the fourth dimension can be conceived but not be seen by our brains. That's ok. Life will go on, whatever direction you figure to yourself...it will keep going and then you have another question: why?

Why to know about dimensions if you can't reach it? By being a scientist or simply a curious person, to answer that. What applications would that bring to your life if no matter how many, it's well know that your life will keep happening. For good or bad. Whatever reality is a collective hallucination or else. Well, I tell you why I went after. It was because I had to understand what I was seeing and why it was recurrent in specific "visions" or "trips" to the so called past. The fascinating aspect, after you endure and surpasses the horrors of some of these past lives experiences, is what kept me studying it. The fascinating details of it, the knots in my thoughts that were untied, the proof that, knowing the past, I could avoid ( and I did, and do) future mistakes. Experience brought me a taste for simple questions. The finals that kept me going was the relief. The past was relieving me from itself. And I will describe the parameters I use to translate what I see to an useful reality. How I learned to define my true experiences from hallucinations or dreams. If there are uses for this knowledge. To me it does have.
