Sometimes we immerse ourselves in things from our past lives as a way to complete them. A few years ago, the "Tonight Show" had a young guest who collected vacuum cleaners. Not very unusual you might say, but wait: this little boy asked for vacuum cleaners as soon as he could talk. He got a Dustbuster for his fourth birthday, and by age twelve, had a collection of antique and modern vacuum cleaners that would be the envy of any adult vacuum enthusiast. It was clear to me that the boy's most recent past life was still "open" and unresolved. It looked like he had invented the vacuum in that life, but he hadn't finished his invention before his death. It is likely that this young man will grow up and make more contributions to this kind of technology.
Past Life Symbols
As a psychic, I often see energy symbols for past lives or past life experiences in someone's aura. Usually, these are for lifetimes that the individual does not want to forget this time around. They may be for lifetimes which are particularly fantastic (high lives), or for a lifetime which offered a tremendous lesson. Sometimes these symbols serve as markers, to identify you to other individuals who have also had that common experience. For instance, perhaps you had a lifetime as a Knight Templar, and now carry the Templar symbol in your aura. Other former Templars would recognize and trust you based on that symbol.
