I think this song is about depression, isolation and certain symptoms/conditions that can go along with that such as depersonalization, derealization, and even dissociation. Not only feeling disconnected because one isolates oneself, or one doesn't feel socially competent, but also feeling quite literally disconnected ("it's just a bird's eye view from up above", people who experience dissociation often describe it as watching oneself from above). When one experiences these things they often sort of feel dead inside, like they cannot experience life fully or experience emotions fully. I say all of this because I suffer from these things firsthand, and I feel Marina describes it perfectly here. Based on what we know about her history, I wouldn't be surprised if she has experienced this to some extent.
