Slash's Mind Cave

I can't remember much from my lucid dream, but I remember being in a room and knowing it's a dream.
I looked around me and everything was confirming to me that it's a dream. I wasn't excited, I was just calmly aware that it's a dream.
I remember about 30 seconds of just marinading in the fact that I'm in a dream.

Next thing I remember is non-lucid. Being in a supermarket with a girl. The girl was either my ex, or an old school friend. It kinda feels like one moment it was one of them, the next moment it was the other. They kept switching. So I'll just refer to them as "the girl".

Me and the girl went into a shop. We were looking at computer chairs, and there was some sort of fuss about a pen. I can't remember what the heck actually happened but it was chaotic.

I remember leaving the store with a wheeled chair and then coming back and passing the shop, and then giving the chair back and getting shouted at, and then I got all upset because I didn't mean to steal. Then all the staff surrounded me and comforted me. One woman said "I believe in yin and yang and stuff like that" and I said "I do to!" while I'm practically crying. Super weird.

Next thing I remember is running through the building with the girl as we were being chased by some sort of monster. We made it outside and jumped over a bush and hid under the bush.

Next thing I remember is spooning with the girl (except I was the little spoon... I'm always the big spoon...) and we were watching something on a smartphone.

Next thing I remember is walking with the girl, and approaching 3 of my old school friends. I saw my friend who has passed away in real life. In my head I was like, "I knew you weren't dead!!" I went to hug him but he backed off. He was still not talking to me.
(Backstory: In real life, we fell out not long before he died. I blamed myself for his death for a while. This dream is clearly showing I still feel fuckin terrible about it)

The whole rest of the dream I was trying to make up with my friend. I wanted so badly to be friends with him again. I think part of me was still slightly lucid because somewhere inside me I knew I only had limited time to do it.

I remember watching a big TV in an outdoor TV area with a bunch of friends and the girl.
When the TV show finished, people started to get up and leave, as if it was a cinema.
I made eye contact with my friend and I said, "please..." and he said something that basically meant "no I don't want to talk to you anymore".
I started crying, then I got angry, then cried again and apologized for getting angry. He walked away.

This dream is looaaaaded with stuff to interpret. I don't need to record my interpretation because it's clear as day to me, what all of it meant.
