I have been thinking about this for quite some time now...

What we think of as "reality" is simply our brain telling us that what we are perceiving is real. However, when we're dreaming, our brain is also giving us that very same message.

Sometimes dreams can be a lot more fun than reality for some people, and sometimes scarier. Generally, people tend to think of dreams as a mere fantasy; simply a creation by the mind. But it's possible that what we perceive as reality is only that, too, since the only way we can possibly think that something is real is through the same way we dream, isn't it possible that dreams can just be another reality, and everything within them is real?

What are your thoughts on this?
