Fantasy World

Today I don’t feel real.. I feel like I’m outside myself, almost as if it’s an out of body experience. Then this got me thinking, because that’s what I do when I don’t know what else to do. 
What if all any of us are is a figment of someone else’s imagination? Our lives nothing more than the fever dream of a stranger dying in a hospital bed of some incurable disease in a world we know nothing about.
That would mean our lives are not only insignificant, they are also not our own. We are living someone’s twisted fantasy.
