Go to sleep with a picture of that person's face in your mind, along with the emotions you feel towards him or her. It may take a couple of nights, but if you are familiar with this person, and spend enough time feeling these things about them, your mind will recognize the emotions that go along with the picture in your mind, and this will eventually trigger your subconscious. Also, you can try writing their name on a piece of paper and placing it under your pillow...this works for some, but you must have a strong conncection to the person in question in order for a name to suffice.
It is not possible to force another person to have a certain type of dream or to dream about any specific thing. If the question is related to the movie Inception, see the attached link for further comment.
think bout them a lot
Yes, if you have sufficient awareness to make choices in a lucid dream, you can make yourself look different while in that dream.
Your dreams are always about your own life. So the "someone" in this dream represents yourself, and the dream is about your own guilt or anxiety.
It means that you are actually fat and just want to be skinny becaues you are obese. So go exercise, stop eating, and then you wont have to dream about being skinny.
The dream is not about this "someone you know." Instead, this someone represents yourself. Your own mind is showing you that you have lost track of a part of yourself.
It's just a dream, if you want to know whether you're attracted to someone in your class then ask yourself.
This dream might have two opposite meanings. If someone is throwing stones AT you, it suggests that you have made someone angry. Note that the "someone" could be a part of yourself, in the sense that on one hand you did what you felt needed to be done, and yet you are angry at yourself for doing it. But if the dream is of someone throwing stones TO you, that suggests that someone is trying to help you by providing basic building materials from which you can build something new and strong. Again, the "someone" can be an aspect of yourself.
Depending on who the "someone" is, this dream might not be at all significant. On a symbolic level, the someone represents yourself, suggesting that this is only a wish-fulfillment dream illustrating your own hope of being married.
This dream appears to illustrate the very wise concept that when you offer to sacrifice yourself, that offer might be taken seriously. When you get "in front of a gun for someone" in the dream, you are presenting your own body as a shield, offering yourself to be shot instead of that other person. The dream demonstrates the seriousness of any offer of self-sacrifice.
You are very doubtful of yourself. Trust that you are doing your best at what it is your doing.
The dream is about saving yourself. Drowning suggests that you are "over your head" in some situation. In other words, you are overwhelmed, having taken on more than you can manage. The dream suggests that it is time for you to save yourself by pulling back and extricating yourself from the situation.
think about it and nothing else repeat it
In this dream, your sister represents some part of yourself or some period in your life. Dreaming of hiding her suggests that you would like to conceal or forget about this particular part of yourself.
