Do you think dreams are signs that are telling you something? like a vision into the future?

Dreams can't predict the future. They're telling you what's on your mind, what you're thinking about, even if you're not aware that you're thinking about these things. You've been dreaming about natural disasters and military takeovers. Well, if you know anything about current events, these two things have been in the news a lot recently. That's how they're getting into your dreams.
