We spend a lot of time asking whether ghosts exist. But perhaps there's a more important question we should be asking first.

What actually IS a ghost?

Is it the spirit of someone who's died? A memory trapped in a building? Some form of energy? Or could the explanation lie in the extraordinary workings of the human brain?

This week on It's A Small World!, Tanya and Mich explore the theories, science and strange questions surrounding one of humanity's oldest mysteries.

From intelligent hauntings and poltergeists to the Stone Tape theory, sleep paralysis and the psychology behind paranormal experiences, we're looking at what people might really be seeing, hearing and feeling.

And we're asking some rather awkward questions along the way.

We also discuss ghost-hunting evidence, unexplained experiences and the bigger question of whether proving ghosts exist would actually prove there's life after death.

Are ghosts evidence of something beyond this life, or simply proof that there's still so much we don't understand?

Expect curious questions, a little scepticism, plenty of humour and probably more questions than answers.

Whether you're a believer, a sceptic or somewhere in between, join Tanya and Mich for another fascinating conversation about the unexplained.

And tell us: what do YOU think a ghost is?

Why have women been so closely connected to the supernatural throughout history?

From Victorian mediums and spiritualists to ghost hunters, psychics and the mysterious idea of women's intuition, this week on It's A Small World! we're exploring the fascinating relationship between women and the paranormal.

Following last week's discussion about witch trials, we're turning the tables. For centuries, women were feared and punished for supposedly possessing supernatural powers. Yet others went on to become celebrated mediums, investigators and influential figures in the world of spiritualism.

We explore the Fox sisters and the rise of Victorian spiritualism, famous female paranormal investigators, and why so many traditional ghost stories centre around women.

And what about that famous women's intuition? Is it a genuine sixth sense, an ability to recognise things subconsciously, or simply a series of remarkable coincidences?

We also ask whether grief makes us more open to paranormal experiences, why people sometimes sense the presence of loved ones who've died, and whether it's possible to be a sceptic while still hoping there's something more.

Are some people genuinely able to communicate with the dead? Or does the real mystery lie in the extraordinary workings of the human mind?

Whether you're a believer, a sceptic or somewhere in between, join Tanya and Mich for another curious conversation about the unexplained.
