Have you ever noticed that there is nothing outside your subjective perception? Everything you can experience, you can only experience through your senses. Without your seeing, feeling, smelling, tasting and hearing there is no world. And also no you.
When all senses stop, there is nothing to be sensed. You are, because everything is. You are you through the world around you and when it ends, your perception, your story, your ego ends, too.
You are the only one in the world.
