Little help with a Lucid dream please

I was walking through this grocery store. 1970's style colors. Nasty dark and light colored browns. I've been there many many times before in other dreams, so it was familiar to me.
And as usual, every one was staring at me. Then, for one reason or another, I was aware that I was in a dream.
So then I started looking and analyzing, "Well that's neat! Interesting why my brain is making this that way and that this way..."
I started to really look around, admiring all the people staring at me and their faces, knowing I was inside my deepest electrical synapses.
Then while walking around admiring all the things my mind had created, I noticed there were a group of 4 people. Two guys - two gals.
And they stood out. They would not stare at me.
All 4 were beautiful and perfect. And not in a homosexual way (for the men) or attractive way (for the women) perfect. They didn't fit all the other parts of the dream. They were an oddity. A hickup. A sector of the boot drive that didn't jive...
When I approached them, they ran to their car outside.
I caught up to one of the guys and being that I knew I was in my dream - I pinned him / slammed him up against the truck (having strength not humanly known - it was MY dream)
WHAT ARE YOU? I asked...
He wouldn't answer me or look at me in the eyes.
IM TELLING YOU A!!! HOLE. TELL ME WHAT YOU ARE!
And still he wouldn't look at or speak clearly to me, only mumbling.
LAST CHANCE! I warned him.
Nothing.
I picked him up by the front of his shirt, flew him up about 40 feet in the air, and asked him once more.
He told me, "I can't tell you." Trembling in my grasp.
TELL ME!
"I can't!" he said, still not looking me in the eyes.
So I dropped him on top of the truck / suv that the other 3 were sitting in, crumpling the bed of the truck.
I picked him back up by his shirt and he said he couldn't tell me what he was.
He got loose from his shirt, got in the truck, and sped off.
I felt as if they weren't from me. Not of my creativity.
They were alien to me.
Foreign.
They didn't fit what my mind was producing.
After that, I woke up, and put every thing down on paper.
Id really like to know what it was that happened. I've never had something in my dream that didn't fit like this, while I was in a Lucid state. And the fact that while being Lucid, He interacted with me has me intrigued as to what really took place or what my mind was doing while I was dreaming.
Thank you all in advance for the help with this.

Sometimes in my dreams there are things that are so powerful and so beautiful that it doesn't feel like its coming from my own subconscious. For example, I don't know if you read the Dark Tower series, but in it there is a small rose that holds all the worlds together. When the characters of that book approach that small flower, they are overwhelmed by the beauty and power flowing from it and think, "There couldn't possibly be anything better in the universe than this". This rose was in one of my lucid dreams one time. As I approached it, I heard several hundred angelic voices singing together in perfect harmony and there was an incredibly intense red light radiating from it. I thought the same thing as you did.

We all have to remember that its not as if everything in your dreams is dependent on you imagining it. Our subconscious simply surprises us or even overwhelms us sometimes. Our minds have unfathomably incredible potential - we only use about 10% of our brains after all. As for those super people, those were just surprises from the depths of your subconscious - doesn't matter if they fit the theme of the dream or not.

I don't know if that helps - I tried at least!

Remember, anything can happen in a dream, just because it doesn't fit in. Even if your not thinking about it, it still happens, though if you think about whatever your thinking in your dream, 95% it will happen.

Maybe it means you're an outcast and people tend to avoid you? I don't mean to sound negative, that's just one interpretation that I got out of it.

The next time you have this dream, you should ask your subconscious what they are and what they mean

Update on this: I found the store. It turns out to be a Trader Joes near me. I walked in the other day and just about schat myself. No flying though.
