What does a dream about a giant snake mean?

I had a dream that there was a giant snake. It was dark green. It looked like a plain old snake, just oversized... I had the feeling that it was going to kill people like how normal snakes eat mouses. But the dream wasn't only about the snake.. There was also this strange glowing golden pyramid. It had an eye on it. What does all of this mean...? I am a religious muslim (if that matters)
