Burke's Nightly Escapades

Location: My home town/a supermarket

The dream started off in a supermarket in my home town. I could see the frozen food section with several meats, as well as the checkout counter which I was currently standing next to. The counter happened to be in the produce seciton where my sister was buying fruits (Later that day, my sister and I bought strawberries and blueberries for my grandmother. I love precognitive dreams)and was looking at some sort of berries. I couldn't tell what they were but they were something like purple. (I'm colorblind )I got bored to I walked outside. I was instantly walking with some of my classmates and randomly looked at my hands. My right hand was normal but my left hand had six fingers, and the thumb was on the wrong side.

I became lucid. I walked over to my friend Zach who was just walking slowly around looking at the ground. "Hey Zach," I said to him.
"'Sup?"
"Not much. Hey, you know this is a dream right? It's not real so you can do whatever you want."
"Really? It looks just like real life. I thought it would be more... dreamy, I guess." At this point, I was wondering if this was a shared dream and I was talking to the real Zach, or if he was just a rather intelligent DC. "Make sure you remember this when you wake up. I'll ask you about it to see if it's what's considered a shared dream. So... what do you want to do? As long as you believe that it'll happen, you can do anything!"
"I don't know."
"C'mon Zach. You have to do something. Maybe you want..." I reach into my back pocket "a million bucks?" I said as I pulled out a stack of money. There were 3 stacks of thousand dollar bills. My mind has good taste!
"No," he replies calmly.
"I'm starting to wonder if your just a DC."
"A what?"
"A DC, or dream character, just a figment of my imagination."
"No, I'm the real Zach." Okay, now I'm confused. We continue to talk about lucid dreaming as I try to convince him to try it when he wakes up, but I don't think I got the message through. We came to a bakery and as we walked through the doors, I noticed another one of my friends sitting in line with a loaf of bread. "Hey, do you consider yourself as an aware person?" Completely forgetting it was a dream and hinking it was real life for a secon, I thought he was a real person but I doubt I would have a three-way shared dream.
"No," he replies
"Then you'll have a hard time doing this." Which was when I woke up.

I talked to my friend today and he said that he does remember me giving him a million dollars and then walking to a bakery together as we were talking about something. I think this constitutes as a shared dream but I'm not sure.
