> I'm very interested what proponents of the idea, that feelings need consciousness to work, would say about my half-unconscious state.

I’m not one of these proponents, but to play the devil’s advocate: The fact that you can’t remember it doesn’t necessarily imply that you didn’t fully consciously experience it at the time.

Maybe it was a different part of your nervous system experiencing them, akin to a BIOS versus the operating system. The brain is a very complex and fractal thing, it is entirely possible that a more basal part of "you" took over for a very traumatic part of your life, very similar, but not exactly, to those with multiple personality disorder act.
