Chain slack

Is it possible for your bike chain to come off the sprocket while your bike is parked in neutral with the steering wheel locked?
Mine came off at a very new girls house who has an ex and I want to know if my chain magically came off the sprocket or if someone fuked with it?
I want to know mostly because I'm not the most mechanically inclined individual and I put the chain back on but it wasn't all the way on. I was pissed and throttled hard to leave and the bike went about 10 feet then the chain popped fully on but not before it disengaged the gear and I went into a vertical wheelie(I've never wheelied before) and went 20 feet into the woods before the bike fell on top of me and bruised my entire left side to to point it took me 2 days to be able to go to the hospital.
Nothing was broke but I have a 5" by 7" large bruise on my side and it killed my gym week.
So I want to know if a chain can magically defy gravity and fall off a motorcycle when it's parked.
I have a 2007 Kawasaki ZX-R 636 Ninja if your wondering the bike.

I'd really appreciate the help because I want to know if it was my mistake or if my bike was fucked with....

A properly adjusted chain that is still good should not be capable of coming off the sprockets.

How old are the chain and sprocket set?

1991 FZR 1000 - built 1040 with race cams, Akrapovic full exhaust, and mild suspension work
2004 YZF R1 - Graves full exhaust, velocity stacks, BMC race filter, and Power Commander. Rear Ohlins. Forks rblt with Race Tech springs and Gold Valves.
2005 20th Anniversary V-Max (0098/2000) - T boost,
