This is more of a philosophical question (touching multiple aspects) that doesn’t seem fitting to no stupid questions.

You already mention the common aspects to it. We put our conscience, our awareness behind our eyes because of how visually focused we are. We put our body center to our torso and heart, because it’s both central to the physical body and the heart and lungs are an noticeable and continuously active part of our physical body.

When you ask you first have to ask yourself, what are you asking for? You used the terms “you” and “self”. Where do we draw the borders of those? Do people put themselves differently or is it the same for all of us? Is it objectifiable or subjective?

I’d interpret “you” as the entirety of me. Including body and mind/conscience. Placing myself in it does not make sense, because I am all of it.

“Self” on the other hand be interpreted as consciousness rather than your entirety. But not necessarily so.
