Do you think the gypsy woman in 'The Flints of Memory Lane' is a ghost? Did the boy imagine it all?

If the gypsy woman in 'The Flints of Memory Lane' was really there, then it seems that she must have been something strange. She was there one moment and gone the next, and gave the boy a very unpleasant smile that has stayed with him forever. The sense of fear he got from her is not a usual reaction to seeing a person standing under a lamppost, so this suggests that it might have been a supernatural occurrence. However, the boy was young and the light at that time of day was not very good. He may have just seen a strange shadow and imagined the whole thing. There is no resolution to the story, so there is no way to know whether he really saw a ghost or not.
