If that were the case, then Bulbapedia would mention it on Torterra's page, either under Abilities or in Trivia. What you are saying simply is not true, Torterra's Dream World ability is Shell Armor. It does not have other abilities that either Overgrowth or Shell Armor, end of story.
If you are so sure that you are right, why don't you present some sort of evidence in favour of what you are saying? So far I have given you plenty of references that refute your claim. You have only made more claims. Not a very good way to convince anybody.
I'll give you one last chance, show me a credible reference (Ideally Bulbapedia, and not some obscure site that I can refute with 5 minutes of research at most), if you continue to do that, I'm going to block you and/or report you.
