Maybe.Nope. Because the supernatural doesn't exist. The supernatural is what happens before the natural is understood.
But what's the "natural" explanation for this?:
My wife, when she was about 14, was visiting her grandmother's farm in southern Illinois.
One day, at about dusk, she was walking along the gravel road from the neighbor's to her grandmother's. The road dipped down to a small creek valley, where a bridge crossed a shallow creek, then rose again toward her grandmother's.
As she was crossing the bridge, she looked off the bridge to her right.
There, standing right in the middle of the creek, was an American Indian on a horse. The Indian looked her right in the eye, nodded, turned his horse around, and started up the creek. After riding about eight to ten feet, both rider and horse just disappeared.
What's the "natural" explanation for that?
Swamp gas from a weather balloon was trapped in a thermal pocket and reflected the light from Venus.
Seriously though, the fading light at dusk and light refraction can play all sorts of tricks on the eyes. Maybe the guy was there but actually off to the side of the river.

Or it could be memory playing tricks on her and how she remembers the incident.

I am sorry but that sounds like something that the government says to cover up UFO sightings.
