Squirrels crossing roads and seeing dreams with your eyes shut

Today I have two questions.

Would it be possible to teach a squirrel how to cross the road at the lights and only when they go green? 

I thought of this question when I read a letter from my Ma (she's my grandmother). In the letter she told me that from their window in Edinburgh they sometimes see squirrels. She said sometimes they were a bit silly because they want to cross the road when there's a red man. So my question is, would it be possible to teach a squirrel how to cross the road at the lights and only when they go green? How? If you can think of any good ideas, please leave a comment.

I would teach a squirrel to cross the road getting the squirrel very gently until we reach the lights. If there's a button for the road, I or the squirrel can touch it, so that the squirrel doesn't run away and so the green man can come very fast. I would do this lots and lots and lots of times until the squirrel knows that it needs to do what I showed it.

My other question is about dreaming.
How can you see if you are closing your eyes when you are dreaming?

What do you see with? Maybe with a telescope that makes you see with your eyes shut. Maybe someone puts it somewhere for me. Maybe with my memory. Or my imagination. What do you think?

That's all that I want to say. Have a nice day.
