So, fun fact, when most people are able to recall whatever incredible idea or artistic vision they had in their dream, they soon realize that it was just their memory replaying something that already existed. An obscure song that you forgot about, a scene from an old movie that you’d think would make for a funny comic strip, etc. Now, this doesn’t mean that people aren’t creative and can’t dream of new things, it just means that your dreams just churn out a vomit of things you’ve processed before.
