Dreams.

 Dream is the prove that fantasy world we always imagined exist. Though only in our subconscious mind. It varies among people. And more creative in  a child's mind. The dead sentence of adult, that some of them couldn't dream because how harsh the reality is grasping onto their lives. I have a theory about dream. My theory is, dream defines who you are. What do you dream about normally ? My dream has been constantly about an adventure. If I put together all of the pieces, I could write a book of it! My dream has never been truly based on my experience, it always open a new chapter in my dream. That I would record in my daily diary. Though the projections of my subconscious always choose new people, and sometimes, the character I read in book of how I imagined them, or even the characters from my favorite tv series, I sometimes dream of the deceased.

Well, I hope it doesn't mean I'll be joining them in anytime soon. I barely live.

Lucid dream. I would very much try it!
