Eh, touchy subject seeing how paranormal events are subjective and the experience vary to person to person. Orbs of light taken by a regular digital camera can be caused by a variety of things such as dust on the lens or reflective light from water droplets can cause orbs to show up on a camera.
Also, if you do believe they are ghost, the theory is that they are made of ectoplasm and project no heat,so an IR shot would catch nothing *shrugs* |
