Alleged ghostly figure of person at top of staircase on left side:

[reaganaut]

its called lens flare - no wonder the country is in the state it is if people think that is a spectre.

Even ghosts need to be careful on stairs.

[Mr. K]

see how there are blurs above and below all the lights?

The ‘ghost’ is just the bottom half of one blur (where the light is just out of the picture, above)

Is the world really getting THIS STUPID?

No wonder aliens won’t talk to us...

Ghostie is walking down the railing, not down the stairs!
