its an a lens dust spec or a small lens flare thats at a weird angle. all the light falls on your body's outlines because of its direction. We use this in VFX for film and its called a light wrap where the characters are surrounded by the environment's light to fake them into the location even if theyre in front of a green screen.The spec under your lip is lit from the front 100% and has no falloff which means its close to the lens, on the lens or a lens flare.

Then again, "ghosts" dont really abide by regular physics so anything is possible. That said, this doesnt look like anything associated to anything paranormal.
