Strange dreams

So... I had this strange dream last night or sometime this morning. I was looking out the window and there before my eyes was a budgie and a chameleon purched on the branch of a very large leafy tree. I watched as the camouflaged chameleon slowly and skillfully opened it's mouth and tried to fit it around the budgie's head. I watched in awe... then before the chameleon snapped it's mouth shut, the budgie turned into a green garden snake. I then switched over to wondering why the chameleon would try and eat the snake and if it was part of the food chain... I woke up really puzzled.

What on earth could this mean?
