The wind makes me feel lighter(both in body and mind), and it makes the general flow in the body better.
I don't think wind could be just one emotion. Wind is so versatile and it can very fast from being gentle to be full of rage.
The question about senses was hard, so I don't know how to answer that one :T_T:
The effect from the wind on the object depends on what you want to do wit the object. For example, if you want to move an object, you focus on only moving the object, and the wind will help you with that. If you are in a battle and your intention is to kill, the wind will help you to slice, slash and tear your opponent apart.
I sit down and the wind swirls around me. I focus on becoming one with the wind, and I try to mix my own chakra into the wind. After a while of doing this, I start to feel that the wind is some kind of extention of myself, rather than just something that is around me.
Senpai, I know some of these answers was a bit lame, sorry for that xD
