what does 'call my own' mean in the lyrcis below? does she mean like someone to phone call? or call by shouting?
Mr. Sandman, bring me a dream
Make him the cutest that I've ever seen
Give him the word that I'm not a rover
Then tell him that his lonesome nights are over
Sandman, I'm so alone
Don't have nobody to call my own
Please turn on your magic beam
Mr. Sandman, bring me a dream
