First paranormal evidence

This is was the first ever piece of footage that I captured and was the catalyst for the formation of my old paranormal research team. What you will see is a light anomaly travelling through the footboard of a bed and then back again. It looks totally different to your normal orbs caught on tape as it appears to emit its own light and energy, in this case I feel its not dust or any other natural particle. This was recorded in a suspected haunted house, is it a spirit or ghost, or is it some other kind of phenomena?
