Spawning Into World Lighting Glitch?

I don't even really know how to explain this one. I went into my creative world to show a different bug but when I spawned in, I had like this giant circle of darkness around me (you can see it in the photo). I didn't get a snapshot of it but there is nothing above my head. I even moved around and it just followed me. I don't know why this is and it's actually really confusing but, gotta report it.
