Photos of the paranormal are extremely rare (see debunking section). Every now and then, we get a weird light artifact we can't explain and post them here.
This photo was taken on the 3rd (top) floor with the multi-spectrum camera. The light on the left is a normal wall light. The streak of light on the right was not visible to us at the time. It's clearly not a lens flare and doesn't have the soft glow of a normal light (plus, there was no other light in the hallway). It's hard to tell if it has a movement trail or not, but the walls and ceiling beams are not blurry as they would be if the camera was shakey.
Ceiling shot. Aside from dust orbs, there is a very bright light arti fact in the upper right of this photo. It is not dust on the sensor and did not appear in any other photos. It's not a line, there are branches. We are unable to determine what it can be.
