Flashforward were alluded to with the funeral parlor Hoffs/Drawlar anagram in S3E22. In S6 in LOST, the flashsideways were an alternate reality (created because of the paradox when jughead went off)….that is evident by the running theme of reflections throughout most of the eps…..mirrors, window panes, etc. The flashforwards started when we see Jack and Kate at the airport and Jack delivers the now famous line “We have to go back!”
But they weren’t flashes into an alternate reality. They weren’t. That was why Desmond was so at peace near the end of the last season. You know how his power was that his mind would move through time and he would see bits and peaces of his future and his past. So he was at peace because he had popped into their futures and seen them all together their in the afterlife. That was the real and true future in the afterlife of all of the characters. They were attempting to imply throughout the season that it was an alternate reality, but it was not. It was the future for those characters.
In ONCE the Enchanted Forest is actually another reality.
