Dreaming about someone you are not close to is absolutely random. I sometimes have a dream about my acquaintances but there is nothing specific about it.
It means that you dream too much
We are alive and not someone's dream, and that is why we dream too.
You ate too much Mexican food too close to bedtime.
The expression "too close for comfort" usually occurs when someone is talking about intimacy. It means that someone is getting too close to you and you are no longer comfortable or accepting of the situation. It can also mean that someone might be doing something that is not legal - and there might be people involved who are 'too close' to the situation to allow transaction.
The interpretation depends on who the "someone" is in your dream. Children are dependent on a Nannie, so negative emotions in the dream dream would suggest that someone might be too dependent on you or too clinging. On the other hand, if the emotional tone of the dream is joyful, it might express your longing to be a parent, or to have someone to care for. On a more symbolic level, the "someone" represents some part of yourself; you might be neglecting some area of your life that requires attention, nurture or discipline.
There are too many possibilities to suggest a meaningful interpretation. A dream of using heroin would be very different from a dream of buying or selling heroin or of watching someone else using heroin.
Just as it is natural to express family affections through kissing, it is natural to dream about people who are close to you. On the other hand, if the "kiss" is too romantic and inappropriate for a family member, it suggests that your ties to the family may be too close. In that case, the dream is your own mind's effort to alert you to your need for more independence as an adult in your own right.
This suggests that there could be a mutual attraction. But dreams do not guarantee lasting relationships. One must build relationships and romance in reality.
You are obsessed with that person. In these circumstances, you must be careful you do not turn too possessive. If you do not have a relationship with that someone yet, be careful you don't resort to despicable means.
Someone too close to their mother.
There are too many factors in this question and too many possibilities to provide any meaningful interpretation. When someone who has died appears in a dream, they generally are alive; otherwise the dream would be of a dead body. As for the beloved man and his child, it is not at all unusual to dream of the person one loves, along with other important persons in the dreamer's life. But how all these characters relate to one another in a single dream is impossible to guess in this context.
A person with autism has difficulty communicating. So a dream about someone with autism most likely would be about problems communicating. The subconscious mind could be telling the dreamer that he/she is not paying attention or is being too detached from the people and things all around.
