Is Snape really that good at Occlumency?

Ok, maybe I got it wrong, but I always assumed that what LV did to Harry at the end of Ootp was not, strictly speaking, Legilimency, but some form of Dark Magic, soul possession or similar stuff. And yes, the love Harry felt for Sirius saved him from Dark Magic just as Lily's love had saved him before, but we're not talking about Occlumency here.

IMO, Snape was not lying. The ability to hide emotions would have been useful 
for Harry, as the whole trap in the Department of Mysteries was prepared on stuff stealed from him and then given to him via Legilmency. If Harry had learned to shut his mind, he would never have dreamed about Sirius.

So we're mixing two things here, imo.
