ghost aura caught on film

It looks to me like light ( as above, in the tree ) shining or being reflected onto the front of your lens or the lens-protector filter if you have one from a place out of picture. When you start the bike possibly a vibration is caused in the tree branches, or a hadeda landed and the branch bounced a bit. Lens flare, I think they call it. That's why people use lens hoods.

Mmm, could be the bike's aura borealis arcing....

The footage wasn't perhaps taken on the road to Damascus? Delmas?

So far the light thing seems to be the best idea, but I can't replicate it. Some people think that it is EMF, but I'd be able to see that on the other videos of the bike, right?

Only if you filmed it from exactly the same angle, at exactly the same spot, with the sun/camera/light exactly the same. Or with the same signal coming into your cell phone at exactly the same time, or with the exact same EMP's in the air, or whatever. The light refraction on your video will replicate itself every time if you could just figure out what caused it. It wasn't a ghost - that much we know at least. Let us know what you find out please.

Imagine a straight line drawn from the sun to the camera. You will need to put the bike (or any other object that will vibrate and change position slightly in a rhythmic way) in such a position that the top of it just touches or go slightly above this imaginary line. So a small movement from the bike downwards will let the sun come over the top of the bike and then hide it again as it moves up.

Words like ghost and belief should not exist in our (skeptical) language!
A possible explanation could be optical interference, when light waves of different frequencies "beat" with each other and form a resultant frequency which is then observed as a different phenomenon.The vibration of the bike could also possibly modulate the sun light to cause a strobe effect.
