Dreams are very odd and mysterious. Some people don’t even think they have dreams. But here’s some information on dreams that might interest you:

1. Within ten minutes of waking up, you forget 90% of your dreams.
2. Everyone has dreams, except in extreme cases of certain psychological disorders.
3. When you dream, you only see faces of people you’ve seen in real life. They don’t necessarily have to be people you know well, so your brain has a plethora of faces in its inventory.
4. Not everyone dreams in color.
5. Blind people also dream. People who become blind after birth can see images in their dreams. People who are blind from birth don’t see images, but their dreams involve their other senses.
6. Negative emotions occur more often in dreams than positive ones.
7. Men generally have more aggressive emotions in their dreams than women.
8. On average, you dream about one to two hours a night and have about four to seven dreams.
