Was wondering if y'all could help me with this dream?

i had a dream that i was at a church sitting down. (couldn't tell who was getting married) but here was only 5 people in the church. which was me, the bride and groom, my sister and her best friend, which are sitting on the opposite end. When i look back i see this huge super dark black snake just starring at the wedding. when i look over at my sister and her friend the little version of the snake is right in front of them i try to talk but couldn't. so i turn around and then I'm sitting right next to them. i see the snake getting ready to attack them and i put my hand in its mouth and it bites me between my index finger and my thumb. as it pulls back with its mouth open it takes my hand hand as if it were stuck. in the back ground the big snake gets closer but doesn't seem to attack. and then i wake up. so can y'all tell me the meaning would be really appreciated.
