Welcome littledreams!

If you could look inside any person's head you will see that we are all crazy. (On this forum you actually can )

Dreams is a way to cope with that so we don't do it outside for real, although that is a Freudian theory, but it would indeed make sense.

Our dreams are our subconscious, emotions and memories in other words they are what makes you! Which is why dreams is the most personal thing there is.

If you dream something crazy it's not you that are crazy but some of the desires that are, however if you dream about it instead of acting them out welll then you are sane
