If reincarnation happens, do you think our 'soul' will be 'us' whatever person we are in, or would we change?

I’m not saying that’s what happens, obviously I don’t know, but d’you think that if we did get reincarnated – like entities or ‘souls’ who come in and out of this dimension or world – that the esscence of what that entity is, like out personalities or whatever, would stay the same, just inhabiting that body as a means of physical existance? Yeah… =)
