Yes, "creepy" things happen the further North you go, but there's a scientific reason for this. When you're on the Earth's surface (or any spheroid), our universe encodes your position as a complex number corresponding to a position on a plane tangent to the south pole. The renderer draws a line from the north pole to this position, and you are displayed where this line intersects the sphere.
This works fine at lower latitudes, but closer to the North Pole even small movements result in large jumps in your true position. Yes, sometimes characters can "flicker" between positions. Yes, sometimes their "insides" and "outsides" will temporarily render as disconnected, disjoint elements.
But this is just math. Nothing creepy. It hardly ever results in daemonic possession.
