Dream of screaming

I was on a lake and was with my dad next thing you know we are riding a jet ski of some kind my dad grabs the throttler while im driving and we take of ending up behind two large boats as im sitting in the shallow sand i look over to see my dad and between us is what i thought was a engine but was really a large white snake and a small orange snake near the white one i jump scared and end up next to another snake that looks like the orange one i jump back again screaming and the snake jumps at me and bits the backside of my arm i scream & shake my arm till some one takes it off then i feel sick and wake from my dream ?
