Clarify focus 12 please

I'm fairly sure that I have a decent level of focus 12 but I just need somebody to clarify how exactly it feels

when I reach focus 12 there isn't anything extremely different but I feel hyper aware, kind of like when you're falling asleep and hear a loud noise and your body instinctively scans its surroundings, except it lasts far longer. Usually in focus 10 I'm very relaxed and oblivious to my surroundings but after the focus 12 countdown I become very aware almost to the level of perception and particularly I become aware of the door, the window and my phone. This perception doesn't really leave the confines of my room though.

Is this the regular state of focus 12 or just focus 10 with extra steps?
