A Dangerously Safe Evil Spirit - Experiencing Oxymorons

"I was sitting in the lobby with my family.
We were all waiting for the upcoming danger --- An evil spirit!

We had to act in front of her as if we don't know who she is. Finally, the doorbell rang. Mustering up the courage, I opened the door, while they waited in the lobby. 

She was dressed in a beautiful white long frock, just like a fairy (while we knew she was the wrong-one--the bad one--an ill spirit!). I couldn't see any magical wand with her, maybe she had hidden it somewhere.

I smiled and welcomed her. Holding her by her arm as I was bringing her in, I said, 'Papa, doesn't she look like Tenzin (my friend)? So cute!!'. Papa just nodded and she faked a decent smile although her eyes said something else...
I think we made sure that she didn't know that we know who she was...!
But before she sat with us, she suddenly asked, 'Where is the bathroom?'
   [Bathroom!!! ?? ]
Mummy and Papa very truthfully replied, 'There are two! One upstairs and the other one is downstairs. (Ek oopar hai aur ek neeche hai)'

I shook my head! Why in the wide world was it so much so necessary to speak the truth to that spirit??? 
Perhaps it was the fear!

I had to make sure that she doesn't go up as we couldn't take up the risk of letting her play some sorcery.
I said, 'Hehe..they mean that one bathroom is on the same floor itself, there, to the right, that's what they call upstairs (So Silly!). And the bathroom that they call downstairs is of course downstairs...but, tenants use that!' (Pheww...that was close)
I had this insinuation. Words like perfidy rolled in my mind.

She looked at me sharply and started climbing up the stairs. ( Dude!!! I had just told her that we don't have any bathroom up there! Still, she was going upstairs...! )
I repeated, 'No bathroom up there...where are you going...? It's here!'
Then she and her evil smile came downstairs. Papa showed her the way to the bathroom. It was dark there. And it didn't even occur to Papa to switch on the lights out there. But a little bit of light was entering there from our lobby. Still!
Trepidation surrounded me. I got up and slowly ran towards them...
And I saw --------- a DAGGER  in her hand!!! (WHAT?)
She was about to pierce it into Papa's belly........  'Hey...NOOO!!!' ...
I stopped her hand tightly and pulled her. Papa moved back.
She turned FIERCE in her behavior as I tried more than my level best to snatch the dagger away from her.   *Shouts*Screams*
She was turning weak. YES, SHE WAS TURNING WEAK all of a sudden as if that dagger was her wand in disguise and without it she was powerLESS, helpLESS...

And then???
            The bad fairy suddenly transformed into a child......
A beautiful child---a pure, innocent child.

And the atmosphere started turning alright. Where did that dagger go? It was no more in my hand perhaps... As if everything was okay now. As if she was the innocent child, Intentionally, she had done nothing.
...CALM...PEACE...

Strange darkness shadowed over my mind and everything turned black .... ! "

I woke up.Whoa...that was a dream!!! Really?
