UFO sighting 2018. Location: Caledon Ontario, Canada. Time: 12:30am
I’ve had this video on my phone for a few years now, and in light of all these drone and alien sightings, I’m wondering what everyone thinks of this.

Location: Caledon Ontario, Canada. 

Time: 12:30am 

My brothers friend was driving home from a friends house around 12:30am in a rural/country area. 

This bright light appears to be following him and then right after he turns around to film it disappears straight into the distance. He breaks. At around 18-19seconds you see a tiny flash of light along the red light on the vehicle. And if you slow down the video you see this thing slowly come back along the left side of the dirt road. It almost looks like being/ shadowy grey figure “walks”and then shines a bright light yet again in the centre of road. 

My brother’s friend drives off. To this day he looks distressed when talking about it and was pretty scared that night.

What could it be? 
What are your thoughts?
