This took place many years ago, when my youngest brother was about three our four, which would have made me about eleven. I only remember it briefly, maybe because I, for obvious reasons, have repressed the memory. What I do remember, is me and my parents being indoors. My youngest brother was outside, on the lower one of our two balconys. I have no idea what he was doing there on his own, considering his age. I can't recall what happened next. I can however recall me and my parents, finding my brother sitting on the floor of the balcony, covered in blood. And if I'm not completely wrong, he was laughing. Of course we tried to talk to him, ask him what had happened, and tried to search for a wound, or at least something that bled. We found nothing. To this day, I have gotten no explaination for the event. Has anyone else experienced anything similar?
