i've kicked myself in my face with my knee during my sleep
I think you're looking for the word 'kneed'. If you're saying that your knee kicked you, then I'm not sure whether or not your knee has a leg, you're on your own for that.
During lunch, my friends were playing something called redhand (hitting each other's hand until the last person remains from giving up). My hits are strong as hell, so then I decided to do a chop with all my might. My friend pulled his hand away and I had a red, swelling side on my right hand that lasted for an hour.
