I had a irrational fear of butterflies as a child...
Also, I remember playing hide and go seek in my backyard at night. The thing is, my backyard is filled with tractors, heavy machinery, vehicles and the likes, so there was always places to hide, more so in the night. We always played hide and go seek tag and were not allowed to lock yourself inside a car (i.e. we could not lock the doors). Man, those were awesome times.
