To dream of a neighbor you actually have represents an aspect of your personality based on your more honest feelings or memories of that person. Ask yourself what one thing stands out the most about that person and try to see how that quality may apply to yourself or to a situation you are experiencing.
To dream of you don’t recognize represents something new in your life that you are always noticing. Positively, may reflect someone you look up to or want to be like. Negatively, it may reflect a problem that is always around.
