The symbolism for protecting your sister is bravery and love
It means that you come in a protective mode. You blaze all your guns and become protective. You like to save your loved ones.
This dream illustrates the dreamer's feeling violated by somebody who should be protecting her/him.
If you didn't have recently images or thougths about unicorns then it could mean that your higher self protects you from your impulsion.
The meaning of the dream depends on its emotional tone (fearful, happy, sentimental, etc.) as well as the content and context of the dream. For example, a dream about watching the sister drive away in a car would be very different from a dream of baking cookies together in granma's kitchen. Very generally, the dream expresses the dreamer's own feelings; it provides no information about the sister or her feelings.
This dream suggests that the dreamer feels a sense of guilt concerning the sister. The dream is not predicting any future event.
Something you know needs protecting.
It probably means that your sister has been giving you a hard time.
The dream is showing you how the broken relationship with your sister is "stealing" your happiness. The image of your sister in the dream reflects yourself. In the language of dreams, you see yourself burglarizing your own valuables because of a value-less disagreement.
The dream means that your mind is trying to tell you that it is time to let go of the past and to contact your sister. This dream provides a fine excuse to open the channels of communication.
this could mean that your sister might like the same guy as well.
Sounds like you have problems.
He's doing your sister.
Shouting in a dream is pretty straight forward to interpret. This is an expression of a need to communicate anger or urgency. The fact that it is your sister in the dream does not necesarily mean you sister is angry with you. In fact it may indicate just the opposite, as it is believed that all charactures in our dreams are just aspects of ourselves. Perhaps you need to sit down with your sister and work out some old business.
