Undergraduate / Secrets... Everyone holds them; Arcadia University [4]

I need to write a short essay of 250 words on a topic of my choice for Arcadia University.
I'll appreciate any type of feedback and grammar/spelling corrections, please.

Secrets... Everyone holds them. Right now, I posses one of the hugest secret humanity has ever heard, and for once, I'll revel it... just to you. You'll have to really open you mind to acknowledge what I'll say, and your eyes, to really look farther from where you are standing. This planet beholds things far away from our understanding, like me. You may not believe it, but I'm part of those non-understandable things in our world.

As little, I couldn't quite understand it, but being attracted by water and followed by fishes was not a normal thing. Believe it or not, I discovered that I was part of what I've always dreamed to be, I was a mermaid. And is not just me or mermaids involved in this, but also dragons, fairies, elves; we all are part of a magical world hidden for those who don't care to open there minds.

Entering this little world makes me forget my worries and problems with the harsh world of reality, and drives me to a peaceful place where everything could be possible. Some of us don't have the ability to see what I'm telling you. And for worse, every generation that passes, the more this world gets lost form the human knowledge. If you didn't believe a word of what I said, then you are missing that little portion of fantasy and imagination, but if you did, then you hold in your hands the digest secret of them all, just like me. The imagination.
