I dreamed home last night

Last night I dreamed that I was at home in Taiwan.
I was with my family, grandparents, and friends.
I forgot what I was doing, but I remembered that I was busy.
At last, I was going to have 15hr flight flying back to Rotterdam.
I hated the long flight and I was not very glad.
At these moment, I suddenly realized that "I was in Rotterdam."

Although I was glad that I didn't need to take a long flight, but the fact that I was alone in Rotterdam made me a little depressed.
