I was staring at the clouds swirling above lake boga, victoria australia; when a small doughnut hole opened in the clouds and immediately, what looked like a perfectly spherical cloud dropped through it, to an elevation just below the clouds. it hovered there for about 20 minutes; then just disappeared as if it was a cloud. the object had a visible energy field surrounding it. the field was cylindrical (in a vertical alignment), just wider the the sphere. the field started at the bottom of the cloud and stopped just below the sphere. the sphere was unnatural looking in that; it dropped through the clouds; it stayed stationary even though the other clouds moved; it had a completely different form to the other clouds; it seemed to move forward towards me (the perspective of it was wrong when compared to the other clouds); and it had the visible energy field.
