I creep when it’s cold, and scatter when sun calls. The more that I gather, the less you can see, Yet when you reach out, there’s nothing of me. What am I?

I see without seeing. To me, darkness is as clear as daylight. What am I?

I never sink, yet I’m anchored tight. I speak in silence, warning by sight.

I can fly, but I cannot swim. You might see me in a conspiracy.

I am used to enclose, but I am not used to harm. You can find me in your local farm.
