ahh yeah, just remebered something freaky..
My Dad's next door neighbour have this kid called Thomas, and when we was about 5/6 he said he had this friend who only he could see. His parents thought he just had an imaginary friend, but where the houses along their bit are, many years ago used to be one big victorian house.
anyway.. in the evening..about 7 o'clock ish, he said the girl (his friend) was talking to him, then we went to go up to her, and fell out of him open window, but landed in a plantpot on the patio below (he fell from the 2nd story) completely fine. and he said the girl saved him.
It's really spookey when he tells you the story though. But it is definatley true!
