The following question was recently posted in the Comments section.
“I often hear berserkers saying they’ve blacked out during gangrs. That’s only happened to me a couple times for very brief periods. What’s more common for me is, in my gangr state, I’m aware of what’s happening and able to remember a some things, but it’s like I’m watching from the outside, almost out of body but that’s not quite the right way to explain. It’s like my mind is a passive obsever who is in no way controlling what the Beast is doing. And my memory of the event will be spotty. But I seldom have actual amnesia, just a loss of control and cant remember certain details after. Is that common?”
This is a matter of both luck and experience. Most berserkers start with complete blackouts and amnesia every time they berserk. With experience, foggy memories start to appear, and the kind of dissociated awareness that is described here. With even more experience, complete awareness and memory are retained.
Some few are just lucky enough to always be aware. That is rather rarer than what I described above, though.
This is all because the berserker state of mind is radically different than the normal human one. Its awareness is very different. The way it lays down memories and accesses them is different. The human mind has to become familiar enough with these differences for it to be able to access those memories, or latch onto the Beast’s awareness.
