Dream of biting

I was dreaming I was laying in the grass at night and a snake slithered over my stomach I tried to not be scared it knew it was crawling over it felt my body heat it reared up as if to warn me but it attacked I threw my hand up to grab it resulting in it biting the top of my right hand but I had a grip in it as well. Out of anger i squeezed it and killed it. Feeling pain in my hand and pulling it's jaws off my hand I see the fang holes.the pain was very bad.
