Where Do I Live?

I live in a universe, where there is a earth, a planet that I live on.

In that planet, there are seven continents, and I live on the first one.

My body is here, but somehow we got stuck on an island.

I am here and he gets his feet stuck in quicksand.

Sometimes I get lost, but my friends tell me I’m right there.

Sometimes I am home, but the people around me says that this is not my home.

I am always here but no one ever thinks I am

So.

Where do I live?
