I find it fascinating that whereas for most religions some sort of afterlife is a major selling point, in Buddhism it's the big nightmare that practitioners strive to put an end to. That said, I've noticed that many Buddhists are in no great hurry to do so and seem to look forward to being reborn with as much enthusiasm as Christians might hope for a future in heaven!
I think that there is a vast difference between "life after death", an afterlife, and what Buddhists and some Pagans believe in which, as you stated above, rebirth.
Many Pagans believe in the circle of life, birth, life, death and rebirth, I am one of them.
I believe that at death the essence of what makes me me will pass to the Summerlands, where it will rest, take stock of the experiences of the life just ended, learn from thiose experiences and await rebirth.
This, to me, is the explanation of things like deja vu and what is seen during past life regressions.
OK - you can now all point out that I am talking bollocks on a par with some of Sassy's and Spuds and ~TW~'s - but hey, it's my belief, but, unlike those previously mentioned, I am NOT asking you to accept it as proven fact.
