I was riding on some kind of Subway or Metro bus, and was inside the vehicle seated facing some of the people in the car. Their faces were morphing in strange ways and I was freaked out about it.

Wondered if I could do such things, I grew my fingers really long and tapped a guy on the head. Then I apologized, and started asking how such things were possible.

me: "What kind of physics permits this? Do you know what an atom is?"
man: "No."
me: "Do you know anything about science at all? Like, do you know the name of a famous scientist?"
man: "I've watched the Discovery Channel."
me: "Really? What shows?"

Then I awoke. Which is too bad, because I was sort of on a roll there.

Had an extended dream in which I was collecting traffic cones off the street with a woman, and talking to her as I did so.

me: "You need to understand that I'm not who you think I am. I'm a person who is sleeping, and I'm merely inside the mind of your friend. What's his name?"
woman: "Roy."

(Note: I was under the impression that this was something that had happened multiple times, that this fellow was essentially thought to be a nut.)

I hid in the back seat of the car with the traffic cones as we drove home. There were police all around.

me: "You'll need to drive as un-suspiciously as you can. So please slow down."

She was upset and continued to drive too quickly for my tastes. But we did make it back to a house.

me: "To make this run faster next time, I need you to prepare some 'Cliff's notes' explaining who Roy is so I can blend in a little better and not disrupt. Put those notes in one place, attached to a suitcase containing some decent clothes so that I can pretty much instantly get going. It would also help to have a photo or something so I know what I look like."

As I was losing coherence, I began trying to go around the house and look at things...opening closets and seeing what was inside. I ran into a black cat in the hallway that I sort of recognized, and I stopped to pet it. It laid down and I was scratching it.

me: "I like you."
cat: (telepathically) "I like you, too."
me: "What's your name?"
cat: "Polar Bear."
me: "That's not what they call you."

(Note: Somehow I knew the cat's owners had given it a different name.)

I left the building andgot into a car with some of my family members, where we engaged in a debate.

me: "What would happen if we drove to my apartment and looked in it? Will we see me there, asleep?"

Suddenly I was in some kind of interrogation room where these odd robots were trying to extract information from Roy. When I told them my real name, they shot me and I woke up.
