memorable

Just had the most realistic dream or dream similar thing happen to me in my life. I was just falling asleep. When I enter horrifying dreams. I Ran into a female dream character she had a jewel around her neck and seemed like she omitted a lot of power some how.
She was warning me first dreams would not stop( I think).
After she told me I will sleep good by doing one thing only," tell me something you will do" she said.
I said something first"don't remember"
She shook her head. and started feeling the ruby I think
So I quickly changed my mind from that to "Insert good specific life changing decision." With this she smiled a pleasant smile, picked my hand up to her mouth And gently held it between her teeth while smiling I think she even said the words 'good' or 'finally' while smiling. As she done this I believe everything went black(or white) and I very slowly woke up in my room.
I'm thinking this dc may be my dream guide? And giving me advice to help in waking life?
I think this because I do have that problem she was referring to and I do need to fix it, she seemed extremely wise. Just please any info on the dc's and dg's from experienced people would be awesome, thanks.
