dreamt or dreamed Riddles

Lifeless eyes on my smiling face and watch your child's sleeping place. In their dreams they hold me tight. What am I?

At the sound of me, men may dream or stamp their feet. At the sound of me, women may laugh or sometimes weep. What am I?

In camps about the centre I appear; In smiling meadows seen throughout the year; The silent angler views me in the streams, And all must trace me in their morning dreams, First in the mob conspicuous I stand, Proud of the lead, and ever in command. What am I?
