I have heard of this in a book about mysteries. It would be interesting to know more information and sightings on this topic. The most interesting mysteries are the weird and odd ones because just think about it... A room made out of amber that just completely vanished! I found more information in the same book also. It talked about green children that were claimed to have appeared in the village of Woolpit in England. Do you know the mystery of the Roanoke Island? If you do not, then it happened in the 1500s I think. The colonists were trying to look for more land, so they decided to travel to North America. John White needed to gather more supplies so he left the area back to England. But when he returned months later, no one was there anymore and there was not even a trace of anything left behind. This still remains a mystery today, although researchers have found more recent things that could possibly figure this out. Let me know any mysterious stories if you are interested.
