This happened to my friends, but its quite creepy.
In 2009 a friend of mine was coming home from a different city at 11pm with his father and 2-3 kms before entering the city, they suddenly saw a white horse standing in the middle of road. He tried to save the horse and severed the car into the ditch below road. As they got out of car, there was no horse to be seen anywhere. He told me this the next day and we found it creepy.
Fast forward to 2015, some other friends of mine were coming home from a different city at 1:30am and doing 140km/hr. They reach the same place near the city border and suddenly see the same white horse standing in the middle of the road. Driver weighed in his options and decided its just best not try to turn. He hit brakes hard and the car just went straight through the horse, skidding. They came to a stop and realised it was a ghost horse or something and ran home. Told me about this the next day we talked.
Weird thing is, either of these friends never met each other and there is 6 years difference between both occurrences.
