I think there are some differences between sleepers and dreamers. Here are a few:
A sleeper closes his eyes; A dreamer sees beyond the visible.
A sleeper lies in one place; a dreamer soars.
A sleeper uses a pillow and a blanket; A dreamer uses his heart and his imagination.
A sleeper sounds like this: "zzzzzzzzz"; A dreamer sounds like this: "hmmmmmmmm".
A sleeper revitalizes his body; A dreamer invigorates his mind.
A sleeper sleeps in darkness; A dreamer dreams in color.
A sleeper wakes up ready to face the world; A dreamer wakes the passion within him.
Are you a sleeper? I encourage you to wake up and dream!
