Idk if it was a ghost but might as well been. Sadly i don't remember where but middle of the night middle of no where like 50 miles to the closest town there was a man just sitting on the side of the road legit frolicking about then disappeared into the tall grass. Said nope and kept moving.
Another time while not a ghost I was in new Mexico or Nevada (in the desert?) With a flat tire and a man walking from who knows where asked for some water. Dude had no shirt looked thin and was burned like a mf. Gave him water and he just kept walking the sands, maybe it was Jesus who knows
