a Dream Character woke me up..?

I'm having more Lucids and i can manage to stay in longer, although i still have some problems. But the thing that happened in an LD this morning was strange.
I was in a supermarket, details not important, then found myself on a train. I was already half lucid. There was a girl in front of me, sort of sitting on my lap facing me. I asked her what year is it. She said it's 1930. I think this can be a good RC, if you can talk to DCs. So i laughed at her and said she's bad at convincing me that i'm not dreaming. She laughed too and i changed her appearance to a girl who i like. I kissed her, now remembering not to close my eyes and completing my kissing task. It felt very real and i liked it. It was getting dark, and somehow i managed to make a light source on the ceiling of the train car.
When i close my eyes in a LD, i always wake up or have a FA.
Not because i thought about this, but suddenly the girl covered my eyes with her hand and made me wake up. What the hell was that? A DC that can wake me up? Have this ever happened to you?

Yep. They can wake you up in a few ways.
I've had one particular DC tell me I was going to wake up in a few seconds because of school. I've also had that same DC scare me into waking up.
Little pest. ;p

I wasn't lucid, but I was having a dream about algebra class, and a girl I was attracted to looked me strait in the eye and said "this is a dream" and my eyes SNAPPED open and I was wide awake.
