What does it mean?

Last night I had two really strange dreams.
In the first, I was riding a horse that I had telepathic communication with. We rode through this beautiful green path, and we understood each other, but that's really all I can recall.

In the second dream, I had three ticks on my leg. I pulled the first two off, but the third looked like it's head was still in my leg. I squeezed the skin, and two stones popped out. Where they had been, my leg was carved out, hollow, and dead, almost like it was made of wood. It was a really disturbing dream, and I feel uneasy when I think about it.

I don't know what it means.
