The Path of the Soul

I've started watching this tv series (which I think in the US is already canceled, like all the good tv series, keeping instead the mindless reality shows), and it's pretty good so far.
Basically there is this guy, a cop, who wakes up one day just to end up in prison, as he is framed for killing a district attorney. He gets to see his girlfriend shot and his sister and her son almost abducted. And then the day ends.
Next day he wakes up, and has a deja-vu feeling that he's been here before, he's heard the same words from his girlfriend for a morning greeting, etc, only to discover that he is actually reliving the same day. He tries this time for a different approach, but still, he ends up seeing his girlfriend getting shot, etc, etc, and he wakes up...and the story goes on.
However after a few episodes he realises that running away won't solve anything, because come the night, he falls asleep, he'll wake up again reliving the very same day. So he tries instead to solve the murdery mystery on his own. For example, there is a post box that he needs to get to as there's a package for him. One 'day', he gets there but it's too late, the package is no longer there. So he says 'no problem, I'll get tomorrow earlier here'. His girlfriend, of course looks puzzled as to what he means.
With every new episode, he puts together more and more pieces of the puzzle, tries new tactics and comes closer to solving the case.
Which made me think of reincarnation, past lives.
They say we come back again and again to learn new lessons, try new 'skins', until we finally get it right and the puzzle is solved.
Every time we come back, even though we don't remember consciously our past lives (although there are ways to remember, through meditation, dreams, hypnosis or even spontaneously), we do carry with us what we have learned from a previous life, the knowledge is there, in us. All those gifts and talents that many of us have in all aspects of life, are there because we have already learned them in a previous life. Have you ever touched a violin, or a guitar, or a pencil and paper, or tried to sing, only to realize that this particular art comes so natural and easy to you, while you do have to struggle to learn all the others.
For me it's making jewelry using silver wire, and also learning languages, particularly one, German. I've lived in Germany close to 2 years and I speak, read and write the language quite well, without having gone to a German school. However I've been living in Cyprus for over 12 years now, and do you think I speak the language? Very very broken, and I'm reading like a second grader. And don't even ask me about writing *grins*.
So why couldn't I learn Greek in 12 years while I've learned German in less than 2 years? I'm reading German novels just like English, sometimes I don't realize the difference in language, I'm that fluent. My grammar might not be proper, since I'm lacking formal education, but give me one week in a German speaking country, and I'll even pick up and speak with the right accent.
It makes one wonder, doesn't it?
