I mean like: How long does it take before you brain goes: oh shit, I exist… I remember, I am a living thing, human, my name is [■■■ ■■■] and my current location is [■■■] and oh shit I’m late for [work/school/event] (or if its weekend, its like: oh… nothing’s happening, life is boring)
Like you know what I’m saying, like the Terminator HUD thing after it reboots and it takes a few seconds before it can identify a target and then recognize its mission… that type of thing.
Or do you wake up and within 1 nanosecond realize the state of your existence?
If it’s wakeup alarm, it takes about 5-10 minutes for my higher cognitive functions to get back online. If someone tells me something during this time, I most likely wil not remember it at all. And it doesn’t matter if I have slept 20 minutes or 10 hours, I’ll still be as groggy.
If there’s a loud sound in the middle of the night, it’s almost instantaneous.
