Well, I totally agree with what you said about the toll sleepiness/dizziness can take on someone's ability to properly assess any given situation.
However, I feel unable to draw the line from being tired and confused to somehow being able to actually reach for a gun, consequently shooting and killing someone in spite of that, you know?
Plus, not wanting to to judge others by my own standards, but when I find myself
frightened by something, and usually even something as mundane spotting a spider does the trick there, the adrenaline rush resulting from this makes my fatigue disappear pretty quickly.
Shouldn't that be the case especially when you have reason to suspect an intruder in your home?
