Something pretty damn crazy just happened to me a few moments ago. I was playing as Trevor, driving a Phoenix at night after beating that mission where you have to defend Liquor Ace and get a grenade launcher.
I was crossing the Grand Senora Desert airstrip, on my way to a garage to repaint and upgrade the car, when I saw a blue dot icon (You know, like the "friendly" ones in missions and stranger encounters) in one of the small empty roads that passes near the airstrip. As I got closer, I noticed it was a red van - And, to my surprise, it was just standing there, stationary in the middle of the road with its doors open and seemingly without anyone inside. I stopped the Phoenix near it and got out to investigate. As I head out of my car, I heard Trevor saying something like "Where are you?".
Suddenly, out of nowhere, I see a big flash and Trevor is violently thrown to the ground for no apparent reason and some man that showed up a few meters behind him, that I could hardly see for more than a few split seconds as the camera turned around while Trevor felt down, said something amongst the lines of "Now, stand still while I reorganize your brain cells". The screen then fades to black.
Trevor wakes up during day-time, in the middle of the railway that crosses the desert, on his underwear, with an oncoming train in the distance and I regain control of him, quickly running out of the tracks while he says "Not again". I thankfully escaped the oncoming train and made my way back to the road where that happened, now in bright day. The Phoenix was still there, but there was no sight of the van or the man.
Has someone else stumbled upon this strange encounter? Will it be further explained in the storyline or something? Because it was really weird.
