Shared Experience is a new series. Fi Glover and guests sit round a kitchen table to share strange tales that turn out to be unexpectedly common. In the first programme Fi talks to people who've seen a ghost. Fi's guests have come from different places, with different backgrounds; they live very different lives. But they have one experience they all share - the day they saw a ghost and what happened to them after. In Britain, strange tales are more common than you think.
