Question. Are these three basically the same?

The reason I am asking, is that I am trying to figure out why my hands haven't seemed like mine this past week. I "know" they ARE mine, but it's as if I'm looking at them through another perspective. Like I'm watching someone else's hands do what they are doing. Like I'm missing a "connection" to them.

Does that make sense?

I feel like a passenger, looking at my hands "through" something.

Is that because there are two parts of me, blended together, right now? Is it just depersonalization? I would guess that co-conscious is another word for blending.

I would value any thoughts or opinions.
