Not necessarily. Your dreams are normally a manifestation of what you has been on your mind. If that someone hasn't been thinking of you, s/he will not dream of you even if you dream of them.
Dreams are about the person having the dream. So this other person's dream is about that person, not you.
According to astrology if someone in your dream is known as a dead person. This is just a dream.
This dream suggests that some part of your self really does not approve of that person.
Dreams are about the dreamer. If you dream of putting someone in the hospital, your mind is using the image of that other person to represent something about yourself - probably that you are overdue for a medical checkup. On the other hand, if someone else dreams of putting you into the hospital, that dream is about that other person, and in that dream "you" represent something about that other person.
If the dreamer actually killed someone in real life, then dreams about that person, the dream suggests feelings of guilt and remorse. If the dreamer only dreams of killing someone, the dream suggests anger with that person.
No. Dreams are caused by functions in the brain when you sleep. If you dream of somebody, it probably means you did something recently with them.
Someone else's dream is not about you at all, but about that dreamer. If someone says something about you in THEIR dream, "you" represent that other person in their own dream. On the other hand, if you dream that someone warns you about your partner, that is quite different and you should pay attention to your own dream. In this case, the "someone" in your dream represents your own mind which is trying to get you to recognize that your partner is not as wonderful as you would like to believe.
This dream only means that the person interests you. Your mind might be using the image of this person to represent something in your dream, such as an attractive, exciting person, or, contrarily, a scary, threatening person. In any case, your dream does not mean that the person was thinking or dreaming about you.
This dream expresses your desire for this person. It only illustrates your own feelings; it tells you nothing at all about the other person.
This dream suggests that you are "sick with grief" over the loss of this person.
This suggests that the dreamer is coming to accept the reality of that person's death.
One need not think about a person while awake in order for that person to appear in a dream. The dreamer's subconscious mind might associate that individual with a particular memory or experience from the preceding day. That individual might symbolize someone or something else in the dream - there are countless possibilities. However, seeing someone in a dream does NOT mean that person was thinking of the dreamer.
