This is from my most recent Lucid:

I somehow became lucid. I walked towards a chubby woman with brown hair. She was kinda pretty. I asked her how she was doing and she said she just got off church. She walked off and as I followed behind her, I stabilized my dream by rubbing my hands and telling myself repeatedly "I'm dreaming". We continued talking and I found out we had a date planned together but neither of us knew when. I found Valery and we started walking. The woman started going into her apartment and I said "You should lose some weight" in hopes that the next time I see her, she'd be skinnier. I also told her "I do love your dress, though". She seemed upset that I suggested she lose weight.
I want to see her in my one of my next lucids so I could ask for her name and why she made such a big impression but how would I go about summoning her? Do I just yell out "I WANT TO SEE THAT ONE GIRL FROM THAT ONE DREAM!"?

Oh and will she be skinnier or no?
