My Sister

Had a dream where I had a sister. 
Most of my dream I was looking for diapers for my sister.

Before that, it was winter and a guy invited me
into his house out of the cold....

And his wife was mad at me
thinking that I wanted her husband
and thought her husband wanted me.

Before that, I was crossing across a beach, 
There were wolves and alligators attacking people.

I was travelling across with a friend I chat with online.
We found a guy that we were supposed to get to. 
I was supposed to do reiki for him. 

Then all those things that I said happened later, happened.

But I know that it's not possible to have a sister.
My mother had her tubes tied after my brother. 
As far as I know, it's irreversible.
My mother is almost 60 years old.
