Spent searching for a fingerprint, a scent, a breath once might exist in my previous life!!!

How could someone feel someone they have ever met yet but really feel that person really exist somewhere? I feel like I’m seeking for something I’m not quite really sure I have faith with but in the same time I also confident that it’s waiting for me. How could this be possible? And there will be no proof until I finally find it. It make me stop recent relation to make myself free for someone I wait. Is it that simple? I don’t know. Don’t even have a clue. I might feel confuse with myself or getting bore with love but why I feel so strong for the kind of waiting. The feeling that told me to wait, the happy, delight moment comes to me with no reason. Just happy for my life and not feel lonely even if I am alone. It is like I am in love with someone but apparently I have got no one. Is this feeling real? Or I just spent time for movie or obsess for love at first sight or the soul mate or the other part of me that haven’t reunion yet? Maybe that the kind of unconscious mind that make story inside my head. I such an imaginary girl!!! Who seeking the love that only exist in those novels.
