Im new to lucid dreaming and what happened last night left me so confused and intrigued. My dream became lucid randomly after interacting with a character in my dream who was shocked when I touched her and realized I was "dreamer" (whatever that means). Its a bit fuzzy what happens next, but I was standing in front of a woman (not the same girl I touched) who looked like Rebecca Mader (pic below). I don't have any fascination with this woman, nor have thought about her for years since I watched the show Lost. I have no idea why she took that form.

Her "You're lucid dreaming, pretty amazing isn't it?
Me: "Yeah"
(she tells me to look at my hand and it comes in focus with more detail than I could ever see in real life)
Her:"You can do anything you want."
Me: "What if I want this to be a sex dream?"
Her (chuckles and smiles): "Sure this can be a sex dream, I like those too, I can be whoever you want me to be"
Me: (I decide that would be a waste and fly around a bit, then land back next to her)
Me: "So I can go anywhere I want right?"
Her: "Yup, anywhere you want to go"
Me: "Eiffel tower!" (effiel tower appears infront of us)
Her: (smiling at me) "Fun isnt it?"

We end up walking down the street together where I interact with a few other DCs and try a few things like putting my hand through walls and growing a 6th finger. These other DCs just seem like dumb drones. This woman seems like she can read my mind and I get this feeling that I've known her forever. So I ask her:

Me: "Who are you anyway, what is this"
Her: "It doesn't really matter"
Me: "What do you mean? You're not like these others. Why are you different?"
Her: (looks visibly annoyed and gives me a drop it look) "I said it doesn't matter"
Her: "Look Keith, you're a good person, you have a strong personality... just sometimes you get a little wild"
Me: "Well at least tell me this. Are you me?"
Her: (confused look) "What? How could I be you? You're you."
Me: "No, I mean, are you my subconscious?"
Her: (lovingly laughs) "No, I'm not your subconscious"

Dream fades and I wake up literally asking myself out loud "Who was that?"

I felt so connected to this person. She literally read my mind at points in the dream and just sort of followed me throughout helping sometimes but mostly watching.

I'm not spiritual or religious.. and I have no idea what happened last night. It was just so... strange.... Best thing I can describe it is like the matrix. I realized I was dreaming and I could tell she wasn't a drone like all the other people walking around, but an "agent" who was also above the dream. I just felt it / could sense it.

So my question... what the hell was that? Im assuming it was my "Dream Guide"? Was I just talking to my own subconscious? It sure didn't feel like it.
