Interoception: BBC Radio 4

For thousands of years people thought we had 5 senses, now it's believed we have up to 33. In this ten-part series, philosopher Barry Smith and sound artist Nick Ryan take us on a journey into the extraordinary world of sensory perception.

In this episode: Eerie premonitions? A feeling you're being watched? A sudden feeling of unease? Do we really have "sixth senses" for things that are... not of this earth? Maybe we do, but there's nothing supernatural about it. Philosopher Barry Smith explores interoception, the mysterious sense we all and asks why it often feels so spooky. From infrasonic pulses to interoceptive heart-beats, there is more going on in our bodies and minds than you might think.
