Anna's and Lexie's dream

Excuse me i have what?

I went to his house cause I knew he was the only one who would ever help me, I knock the door and no one come out it wasn't a surprise cause is weird when he open the door, I decide to give up I turn around to leave and I hear the door opening I saw him standing here and he told me:
-Babe are you leaving with out saying goodbye?
-Coltin! I hug him so tight it was the first time I was seeing someone that I truly love I didn't have anna so you will say
-what's the problem did you fight with anna again?
-no this is different and I need your help
-ok first you will have to tell me what is it!
-ok,remember that j told you I was going to the mountain? Well when I was there I found a cave and in that cave was a puppy, I bring him home but I didn't though he will ruin everything,after a week that he was there weird things start happening to anna, three days ago after I take a shower anna get in the bathroom and she was in there for two hours so I decide to go get her but when I open the door all I saw was her phone and there was a picture where the dog was taking away anna
-okay look at me, I can't bring anna back but you can!-how I will bring her back if I don't have powers to do it!
-you have them Lexie but you didn't know about them, so I'm telling you this, you will be able to have your sister back using your powers when you find yourself, and when you do I will help you to get to anna but now I can't now you have to go!
He took me out of his house and u try to come in again but he didn't answer.
Now I'm alone with a question on my head"why is this happening?" I don't know how I will find myself o have no one my sister is gone and Coltin say I can bring her back using my powers but I guess I won't be able to do it cause with out her I'm nothing she is my sister and now she is gone and it's all my fault......
