I was leaving my parents house with my two young children, we were heading home. i noticed something flying over their neighbors house. it began to move towards my parents house at a very slow rate. i thought it was possibly a farming airplane, since they live in the country. i heard no noise and noticed it was shaped like no other airplane i have seen. as it passed my vehicle i noticed it was triangle shape and had three lights. while passing the object i got a little light headed, nothing major, but i did feel odd. i called my mom to see if she could see the aircraft . she headed outside immediately. she didn't see anything or hear anything. i turned my vehicle around to see if it was still visible. i drove in the direction it was heading and i could no longer see the flying object.
