Answer:
I can wake you up in the morning but I require no electricity or winding. What am I?
You may enter, but you may not come in. I have space, but no room, I have keys, but open no lock. What am I?
I fly when I'm on and float coming off.
I am a shower that lights up the sky
Without me everyone would lose their head.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
