I too have died in my dreams.
The most real one was somewhat recent, a couple weeks ago.
I was in some type of Oceans11 team that steals sh!t, and we were stealing from the mafia and they caught us in the act and cornered us in different spots and we all died like an epic movie ending.
I remember specifically knowing I was going to die, so I layed down on the floor as the guys approached me to kill me, knowing I was going to get the fuck beaten outta me. I remember getting blasted in the skull with a blunt object (maybe a foot). I wasn't sure as I was laying there just relaxing and closing my eyes thinking of my last minutes of being alive. I could actually feel the beating too, I was kicked in the throat and I woke up gasping for air and I could feel the ringing in my ears from the blood rushing to my head due to the blunt force trauma.
That shit was crazy, and I think getting beaten to death would really **** after that.
