The white horse might represent freedom from your ex, especially sexual freedom. Yet the meaning of the dream does depend on what sort of white horse you saw, as a worn out white farm horse would mean something quite different from a magnificent white charger, and a sweet white mare would have a meaning distinct from that of a white stallion.
What does it mean if see a horse with wings..at the end of a dream with red lights
You have a strong desire to ride.
The meaning of this specific dream depends on the emotions you felt during the dream. Often red eyes on the any animal, whether it's a horse or a wolf or dog or whatever, suggests anger or rage or even demonic possession. In that case, the white horse would symbolize something that you are very much afraid of, or a problem that is threatening to get out of control. Alternatively, red eyes can simply mean that someone's very tired or worn out. In that case the white horse might represent a hero's horse, like the cowboy who rides into town on a white horse or the knight in shining armor who writes on his white horse to rescue someone. In that case the white horse represents yourself and your efforts to be a hero and to help everybody else. But the red eyes suggest that perhaps you have worn yourself out trying to be the hero to too many people too often.
Well it depends, if you mean white as in dominant white, then no the entire horse would be white. If you mean white as in a grey horse gone white, it is possible, though not seen much, typically the mane whitens along with the rest of the horse.
Nothing. Is just a dream you had.
White
the dream is becoming more intense and threatening, just as a growling bull is more threatening than a horse.
If you didn't have recently images or thougths about unicorns then it could mean that your higher self protects you from your impulsion.
This seems to be a dream that represents a fear of bad dreams, or "nightmares." The subconscious mind presents a literal picture of an attacking horse to symbolize a "night mare." Alternatively, the dream horse represents something like a horse. For example, the dream might be about something one might ride, such as a bicycle or motorcycle.
Unfortunately it can mean the horse is going blind
The white background of the Japan flag is representative of honesty and purity.
To see a horse in your dream symbolizes strength, power, endurance, virility and sexual prowess. It also represents a strong, physical energy. You need to tame the wild forces within. If the horse is white, then it signifies purity, prosperity and good fortunes. To dream that you are being chased by a white horse may be a pun on chaste. Perhaps you are having difficulties dealing with issues of intimacy and sexuality. To see your cousin in your dream represents something or some aspect of your character that is somewhat familiar. Perhaps you need to spend more time in cultivating and developing some emerging ability or character. Source - dreammoods.com
