This is the slang term based off of a YouTuber named dream when he is faced with controversy he throws a temper tantrum on Twitter. So the word means a person that reacts poorly to situations or controversies and likes to throw a temper tantrum on Twitter about it.
Person1:Did you see that don got into a controversy today

Person2: yeah he was being a dream about it

When a fan of the Lego Bionicle toy franchise (usually those who are old enough to remember when the first-generation (G1) Bionicle sets were sold new in shops between 2001 and 2010) excitedly thinks they have found themselves in a Lego store selling Bionicles, only to wake up and discover they were actually sleep and they had merely experienced ‘The Dream’ again, resulting in a crushing feeling of disappointment and longing for the past.
I had The Dream again last night and I’ve been thinking about Bionicle all day. I wish I could go back.

The thing your parents and teachers encourage when you are a kid, only for it to start getting crushed by life.
Kid: "mommy, I want to be a doctor when I grow up"
Mother: "yes son you can achieve anything!"
~kid grows up to the last year of high school~
Kid:"mom I am going to be a bartender"
Mother:"what happened to your dream of wanting to become a doctor?"
Kid:"life.... and my grades"
