Snakes and Ostriches

I dreamt I was lying on a bed against the wall at the edge of this field. As I looked up, I could see several ostriches walking around just a few yards away. A voice or a person was pointing them out to me and I remember thinking or saying to myself: Ostriches are pretty agressive and dangerous. Why am I so close to them. At that point a few of them walked over to me and stared into my eyes. I covered my face in anticipation of them pecking at me. They began to do so, but when I lifted my head up, I was now inside some sort of zoo cage. The zoo keeper was now pointing out a snake and talking casually about it. Again, I couldn’t understand why I was in a cage with a snake. The snake came up behind me and began biting me in the back, and then I woke up.
