this dreams been bugging me for a while...

I had a strange dream a while back and couldn't make heads or tales about it, its been bugging me ever since. here`s how it went, I was walking under a big oak tree during the day, and was just looking up at the leaves. then I saw the tree let go of one of the leaves and it floated down to me. after I caught the leaf i felt kind of at peace i suppose... then I woke up. is there anyone who could tell me what this means
