Narrative:

Reporter was instructing a cfii candidate, practicing basic attitude instrument flying. As I removed my view limiting device, a red/white small aircraft Y came immediately to my attention. I banked right and climbed. The small aircraft Y did the same. We were level at 3500 ft on an ese heading. It is my opinion that the small aircraft Y was in cruise at the wrong VFR compass altitude. The small aircraft Y circled and appeared to give chase, we climbed and departed area to continue instruction.
