Yesterday's Dream

Hello Hisako,

There is a difference between your tongue sticking out and hanging out. When you stick your tongue out you are usually being rude. When you see something very desirable your tongue hangs out.

When you use because to explain something which happened in the immediately preceding phrase you should carry on the sentence with 'because' not start a new sentence.

Hope this helps

Yesterday's Dream

✓ But in reality, she got married recently.
(This is not incorrect. But would be better written as: "But in reality, she recently got married.") 

✓ In my dream, my boyfriend looked really happy and his tongue was sticking out.    

✓ Because she is hot and beautiful!

And she said to me " Are you a his girlfriend? Hmmm....."
(Again, not incorrect, but would be better written as: "And she asked me, 'Are you his girlfriend?' Hmm."

✓ She obviously looked down on me!
(Not incorrect, but I would write it like this: "Obviously, she looked down on me!" Or, "She looked down on me, obviously!")

✓ He was still smiling and I was frustrated!

✓ What a stressful dream!

I think I would write it like this:

Yesterday, I had a dream about a famous Japanese actress who was interested in my boyfriend.
However, in reality, she recently got married.
My boyfriend looked really happy in my dream. His tongue was sticking out; she is hot and beautiful.
"So, you're his girlfriend, huh?" she said.
Obviously, she looked down on me.
Meanwhile, he was smiling whereas I was frustrated!
What a stressful dream!
