very rarely now, but yes, it is known to occur.
Funnily enough, this morning I had a dream where me & my pops went into this bizarre rock bar based on the coast, my pops asks for a beer, then calls me for mine, I tell the bar man, he cards me.
So I'm like cool, search for my ID, he takes it, looks at it, drops it on the floor, says nah and walks off. Leaves my pops hangin with a pint.
Theres a bit more to it, but basically, dude later tries to give me the bums rush, so I shoot him in the head. He dies, everyone cheers. 'Nice one mate, Geoff was a cunt'. !!!!!
I awoke from this dream today, and it's fucked with my head a little. thought id share.
