Dream of child, screaming

I was in one of my old houses from when I was a child. I was attacked by a boa constrictor and it wrapped its body around mine, squeezing till I thought I was going to break. I also was attacked and bit on my wrist by a poisonous snake. I freed myself from the snakes was running around the house, my sister was there, I was screaming for help. The boa constrictor some how followed me into my old bedroom and trapped me there.
