Snake dream? What does it mean?

I had dream last night that i had a pet snake. I was looking after it however i was told that it doesn't like being in a cage and instead free in the sink. I had to fill the sink with cold water but i forgot to put the plug in so the snake went down the drain but his head was too big so that didnt. I managed to get it out, plug the sink, then put the snake in cold water. What does this mean?
