Good evening Sarlet,
"I see the person I wish to be smiling at me": it all depends on the smile: mischievous, beaming, happy, encouraging, or sarcastic, mean, mocking, ironic
"to turn toward a person who is much smaller and appears much younger than him": is or turns toward another person different from you
“He speaks to him”: you are talking to yourself, you are having a dialogue with yourself
He barely says hello to me
"but I see him kissing her": a farewell kiss, a new breath, a breath of life
What does this dream mean? Also, it's located right below my place, on the sidewalk.
Summarize:
You accept it with a smile, encouraging yourself to move forward by accepting the decision, the choice he made to go to another woman.
You are having a dialogue with your inner self, downplaying the matter, ignoring it. You have a new breath of life, spirituality, and other aspirations because you have reached a higher level than him.
With affection
Ladysally
