Chapter 1 into the ocean
________________

Cold....it was cold..all I could remember was the water coloring with my pale skin..

Why can't I wake up?what is all of this commotion?how did I got into this situation?I don't fully remember at all....
I'm scared...not scared of not just remembering...
But I'm more scared of the ocean,or was this an lake?....

I don't know any more and I guess this won't make a difference for now..

Somehow I'm dying?but I don't feel any water coming into my lungs at all

C'mon remember something!
...
Ah I see,I was....in my home,actually not doing to mutch,it was an  Halloween night,I love Halloween but the country where I do come from we don't do Halloween,But then how did I got here in the first place?

((3th person pov))

No matter how hard the human girl tried she couldn't move to mutch or even,open her eyes,till them there were no hostile creatures around at all,just some fishesswimming around as the sunlight of the sky poured trough the clear and gentle calm ocean water,making some rays go in the water.

Truthly the underwater world was something like another world,it would even be hard to tell if it was the same world as the lands,they truthly looked like a whole different world from each other.

It didn't took to mutch time for the human to gently lay down on the soft sand that just puffed up a bit by her landing and sprayed around like golden particles and soon they stopped and disapeared on the clear,salty water.

The human long black curly locks danced around a bit on the water and soon floated by a bit,it was like she was just asleep and nothing more but it was more then just begin asleep,but truthly she wasn't dead at all,but little did she knew that her comon and boring life would change a lot and maybe forever,this isn't her world,this isn't even her multiverse..

This place is something that she dreamed,and though that it would possibly exist but never really truly tough it would be so true.

Her body,it felt like it was now burning,she groaned softly,she couldn't even move to mutch at all,even when she was falling in the water some minutes ago as well on the sky,maybe that part was just in her mind,but now she couldn't think to mutch on any other things when the pain worsened,and it itched all over her skin like a kind of sunburn.

But then it worsened up when she felt her bones and inside her body change,the feeling was like ice spreading trough her body,it was to mutch cold that it burned,she started to scream but no sound came,just bubbles from her pale pink full lips that went a bit up on the water and some disapeared.

Just after some minutes she panted and gasped slowly moving her body but just not to mutch,she had got exhausted about to fall asleep into darkness.

She couldn't even fell her legs any more,not even her skin...what was happening to her
