Please help me figure out what it meant...

I just had a really weird dream. It would mean a lot to me if somebody could help put my mind to rest as to why I had this dream...

Myself and my little sister are in the house, the phone rings, its my dad from work. He tells me of a friend of his who can get free raspberry buick motorbikes. When I tell him that I'd love one, it would push me to get my driver's theory test done, he decides he wouldnt be able to get one.

Meanwhile, at some point earlier in the dream, the doorbell rang. We could see out the door, and my mother said it was 'uncle Jack' (my name is Jack)...my little sister was searching for the key to the door.
Something happened then, in the sitting room, with myself and my parents...my dad is home again...strange that...I cant remember what exactly happened but what I can remember is walking away in a huff. I stared out the glass of the front door and mimed boredom, tapping my watch etc. as my sister was still looking for the key for my 'uncle Jack'...finally, she opens the door, and she's really excited to see this man. We both hug him, although I havent a clue who he is, I know he is my 'uncle'...

When I awoke very shortly after, it took me a couple of seconds of rethinking the dream, to realise that that man, in his late 20s, early 30s, with his eyebrow piercing, blondish hair, denim jacket, was me. I'm only 20 recently, and this man was clearly a few years older, although I'm certain he was me...


But why did I dream about an older me? Why did it take so long for my little sister to find the key to the door, and why did she recognise him but I hadn't a clue who he was?

twas quite freaky....wud mean a lot if you could tell me what it meant....
