Grischkaja's world of dreams and mysteries

I post this dream a part, because it contains some sexual/offensive stuff.

I'm in my old school. I look at a poster but can't read anything. It's cold an grey outsides. A very sexy girl (we used to go to the same courses) walks towards me. She swings her hips and moves very slowly towards me. I'm not really noticing her, because I'm trying to decode the poster. She starts a conversation with me:
- Did you noticed that I lost my pants a few seconds ago?
- What?
- I said: I lost my pants and revealed my sexy body but you didn't noticed it. But in the meantime I put it on again.
I'm looking down and see that she has still her pants. I think she made a joke so I said to her:
- OMG, Why didn't you informed me previously? Now I missed my chance to see you half-naked.
She smiles and says:
- There is something I want to add: while losing my pants I fell on my ass and now it hurts so bad. But I know something what we can do to forget about this "incident".
She gives me a challenging look and whispers something to my ear. I don't hear it, but I already knew what she's going to say
She comes very close to me, I feel her hips against mine.
- You have to know that I can still put my pants down, just for you, so that you can see what you missed..., says she
I realize that nobody talks in this way, that this can't be real.

I immediately awake. I don't know what to say nor what I have to think about this
