Please answer this: What does my dream mean?!?

It was like me and my brother were kids again, and we were playing out in the woods. This lady came up to us, and ushered us into her house... in the middle of the woods. When night fell, my brother came to me, and he sat in front of me and tickled my toes. I laughed softly, and pulled my feet back after a while. I was staring at his fingers, because he was still tickling toes... not mine! I tapped him on the shoulder, and whispered fearfully, "Those aren't my toes," and he looked back and screamed. I looked back, too, and it was the lady! The lady led/dragged us to this big wooden table, and set us on it. Apparently she had been sharpening a knife, because I could see a really really sharp one on the table, and she put it on my brothers neck lightly. I put my fingers there, as if that would protect him, and she turned to me. The crazy lady put the knife lightly on my neck, and I could feel the cold metal. My brother screamed, "Don't!" and the lady swung. It was weird...
