I have no doors but I have keys, I have no rooms but I have space, you can enter but you can’t leave! What am I?

I am the one who remains awake when you sleep. But I need to rest when you awake. Who Am I?

You can win me and lose me but never buy me
You can not eat me and never want to part with me
I can make you cry or bring you joy
I am not a machine and definitely not a toy
You keep me but i am not forever just yours
You might find me in a case or on a shelf next to a vase
I am hard and i am tall if you bump me i am sure to fall
I am made of different materials and am at many events
If your lucky and fight hard I might be yours
What am I ?
