text: this is about harry potter. in the 7th book will dumbledore  tell us that his death was fake,to fool voldemort   talk about stupid questions...  anyway, no, dumblebore is dead and he will stay that way. harry can communicate with him though, using the portrait that appeared after his death.  it's more likely that snape is indeed loyal to the order of the phoenix and that him killing dumbledore was something that he and dumbledore set up together (remember their fight in book 6, the one that harry overheard?) knowing full well that this would ensure that  a) voldermort would finally take a chance to actually kill harry, something he wouldn't do as long as dumbledore was still alive and b) voldemort really believes that snape is a loyal deatheater, thus making sure that voldemort doesn't expect snape to kil him. which will of course happen, probably helped by harry. and probably snape is going to die in this attempt.
