Reincarnation is a big deal for most people at the beginning of their spiritual awakening. It's an intriguing concept and fun to speculate about, but has nothing to do with what's happening now aside from some tendencies you've carried over from other life experiences.
If you've not already clicked it, that link at the beginning goes to a Wikipedia page that covers the specifics better than any other site I've seen. The links from there are amazing. I'll not attempt to compete.
Belief in other life experience is like believing in air, water, sunshine, or gravity. Dwelling on it is not going to help you become acquainted with your God-Self. It's a pretty distraction. Just be here now.
I know, I know, ego-mind says you were a big shot in another life, so it must be so. Happens all the time. No reason for embarrassment. Be patient with people who go on about this sort of thing. It's normal and humorous. I believe we all experience so many incarnations and reincarnations it is meaningless to speculate about specific identities.
Belief about reincarnation is interesting in that some folks conceive it as a time-bound progression in which we become incrementally more spiritually aware, while others see it as a series of fits, starts, setbacks and leaps. The three steps forward two steps back sort of thing.
Christians say they don't believe in it, yet believe they'll go to heaven or hell, which are just other life experiences when you think about it.
After giving it some thought, I believe we all live an infinite number of lives, the number increasing exponentially forever. This conclusion is reached by a number of paths. Let me explain.
If you read about hypnosis, and particularly Ericksonian hypnosis, you'll get the idea that what we think is "real" is just our interpretation.
Sure, there's a consensus trance in effect that causes us to have mutually defined experiences of the world influenced by groupthink, but it is still a highly subjective experience.
You are creating your experiences of the world according to your beliefs. You can change beliefs that don't support you.
Get a book about neuro-linguistic programming or NLP and look into how you can change your beliefs to conform with your goals or as NLP practitioners call them, well-formed outcomes.
Some NLP practitioners are also hypnotherapists and they can be very effective helping you modify your beliefs so they serve you well.
Your beliefs about reincarnation or other life experiences influencing your present life may not be serving you very well. You decide.
