Forum:The true end of fate/stay night

I have a question: is it true that the true ending of fan is HF true end? Since some people argue that nasu stated so, or is last episode the true ending? Another thing is are shirou and saber reunited on Avalon after death? Also,something I'm last episode is bothering me: 1)the story says that they meet again at the end of the dream so is there meeting nothing but an illusion? 2) this is mentioned: "In this ending, he became someone else's star, continuing to spin around the world". What does that mean? Thanks in advance and I hope to get am answer ASAP since this is very important toe.
