Explanation for visions

No, I swear I'm not insane or mental. Recently when I see or think about people I know I get hit with visions about them in different time periods (even WAY back as far as BC). More than that, after I get these visions I see a spirit (not physically in front of me) that is this person's love. I'm not joking, I seriously need you guys to help me out!!!

 Please leave me a link or a legend from some culture that can possibly explain this!!!!!!

Some people have good imaginations, you sound like one of them.

I don't blame you. Would you consider speaking to someone in the Catholic Church?
