What does it mean when dreaming about snakes?

I has a bad dream last night about a party with my relatives somewhere like on a beach or it could be a flowing river where there are snakes and crocodiles. I saw my Uncle was constricted with a huge albino phyton and both my uncle and the snake was eaten by a crocodile. all my relatives were shocked. And before my Uncle died i saw different kinds of snakes inside my room...i also saw a cobra a small one and a differnt snake somewhat like a sea snake. Hope you can interpret my dream. thanks!
