I think it's very important to take dreams into account. Being able to Remember all we dream, although sometimes it doesn't happens, can give us a lot of information about ourselves that maybe consciously we are not able to see.
While it is true that interpreting them is not always easy or we don't know how to do it properly, knowing what we have dreamed can tell us a lot about what we crave in that moment, what worries us, or even what has marked us in the past, such as situations or phobias that haven't overcome.
In this opinion it is reflected that I agree with the theory that Sigmund Freud had about the relationship between the conscious and the subconscious in dreams.
