LRT Onward Mystery

It's raining since the dusk. Raina is standing by the window watching through the glass. It's all blur before her eyes due to rain drops falling through the glass. Still she is terrified thinking of the yard which is far far away from her sight. One month ago, she has started her high school life. She thought it would be like..... first spring of life, having new friends, hanging out with them, hot chocolates....being always together...no matter what....but somehow it's not exactly as it seems...At that point, a cracking sound of door gets into her thought....She looks behind. It's her mom.. "Turn off the light, Rosy. It's almost dead night...What are you doing...still? ", the mom asks. "It's started raining heavily,   it makes a light, rhythmic, tapping sound, it's amusing a lot , So, Mom. I couldn't get to sleep" "Oh...yeah. It's getting colder again...Well, let me pull the curtains." But while pulling the curtains, a thought came to her mind..."Hey, Are you still seeing those dreams?...Is everything good at school? You know you can share a lot...with me...If you want to...I'm your Mom. Ok?" "I know, I understand...I'm good. Everything is just fine. I'll just sleep now...You may go." "Umm...alright. I will just leave then... Come here. Give me a hug." Then, giving a kiss to her forehead...the mother leaves the room.  After that Riana closes the door and falls upon her bed to sleep. It's not true that everything is fine. On a rainy night, She used to love lying in bed listening to the rain patter on the roof and her mom would sing  Pitter-patter lullaby for her. All are memories now. Besides, nowadays she is seeing things in her dreams... Specially, she still sees those dreams...that she has started watching just one week before...Still, as usual she keeps saying  as whispering to her own ear , "Thanks Mom. Good night...".  Then she tries to sleep over...again and again. But she can not...At last, she stops trying to sleep. The whole night she tries to recall every incident of last week...Then she starts to ask herself "What is it? Why is it so misty...I don't understand...What does it want from me.... Outside there, the storm was still raging against everything beholding it's own natural feature..... (One of the best quotes related to rain, is this by Emily Mendez.... “Rain has a regular, predictable pattern, This unique rhythm can be used in many areas of life ”  )
