Have you ever been able to operate socially from within that state?

No.

Because how is it possible to speak or communicate when you are not aware of self?

I don't know. But there are cases of people, like enlightened masters, who do in fact do that. I think their behavior is largely automatic by that point (that's not to imply 'unconscious', but rather that no conscious intervention is required in their human behavior to be in concert with the unity of the universe). That might not be the right way to say it. More like: they are operating in such flawless harmony with the universe that there is no distinction being made between themselves and any other selves they appear to be interacting with. It is essentially your consciousness residing in the buddhic, or violet ray subdensity of yellow ray while physically conscious.

Also, is this state accompanied by "bliss?" I assume that whatever we call bliss here cannot be related to emotional happiness.

Yes, it is blissful. I'm not sure how to characterize it beyond that. Perhaps it might be described as non-intellectual and complete acceptance of the present moment.
