Question: Why do we dream?

Babaji:

Dreaming is a very peculiar state. There is no definite explanation for dreams, except that it is definitely an illusion within the mind. In a dream you can create a huge scene with many characters, then suddenly when you get up, you see that you're just dreaming. It may be from something simple like strong food, so sages have recommended to take a small amount of light food. Or from a strong resolution of the mind. The dreams themselves will vary so that some may be strong and appear very vivid and they stay in your mind when you awaken, while others may be weak and indistinct and difficult to recall later.
