What are choosing dreams about?

Hello all!
About 2 weeks ago I had a very existential lucid nightmare that I can’t get out of my head. It’s to the point where it has been effecting my waking life. I need some outside help making sense of what it could mean.

For context, I have existential issues involving what my purpose in life is or even if I am supposed to exist at all.

So it began in a sort of black void with a warm colored aurora in the sky. Directly in front of me there is a hooded man with his left eye missing that looks like an older grizzled version of me. Same look, voice, eye color, scar on our upper lip, everything. He is looking into a circular stone fountain looking thing with a bonfire positioned on a raised platform in the middle.

Around him in every direction as far as I could see were hundreds of thousands of gravestones. All of them had a vague “endings” written on them. (For example, “The Swiss Ending”, “The Atomic Ending”, “The Fantastical Ending”, etc.) Some were filled in while most had empty holes in front of them.

I approached the man in the middle and politely asked who he is and where I was. He simply responded with this,
“You know where we are, this is where we all go to die. Now find your grave, I’ll help you out when you get there.”
I responded with,
“My apologies, pal, I’m not dead yet. Who did you say you were again?”
“Does it matter? We’re all the same here anyway.”
That is when it occurred to me. All these graves were for different versions of me. From different realities or universes I don’t know. I was fairly certain I wasn’t dead and this was all just a bad dream so I decided to explore and possibly see which gravestone in this labyrinthine graveyard was mine.

As I walked, I started to feel a tug from my chest, like my heart was being pulled in a certain direction. I followed the pull for what seemed like ages. Eventually the graves just stopped except for this one gravestone sitting alone just outside of where the rest of them lay. As I approached my soul felt like it was it was sitting next to a cozy fireplace, so I had the feeling that this grave was mine.

I eventually got close enough to read it had it not been for the dust and debris that covered it. It looked old and dilapidated yet it still had an open plot in front of it. I brushed off the dirt covering the gravestone and what I read chilled me to my soul.
“The Bad Ending”

The old man came from beside me.
“What an unfortunate soul this one. Feel real bad for him, you know?”
“I think that’s me.”
“What? No, it couldn’t, he’s not-“
He looked at me, his face grew grim.
“Oh shit, you’re not supposed to be here yet!”
He then grabbed my face and I felt my brain shock like it had just been struck by Thor himself.

Then I woke up. Sweating, crying, and white-knuckled. It’s absolutely fucked with my mind ever since.

I'm a 30 year old man. I was having a dream where my brother and I were waiting in line at a supermarket. We had to make the flight and it looked like we'd be running late. I decided to go to the bathroom and started peeing. I immediately woke up and realized I had actually fucking peed. Not alot, but enough where it got onto the sheet through my pants.

What the fuck lol.

Is it just me who prefers dreaming to real life? I have chronic migraines and chronic fatigue syndrome so maybe that's why. Sleep is my happy place where I can have whatever I want and do what I like, then I wake up and realise real life can never match the feeling I get in my sleep. If there was a pill that put me in a coma and let me dream until the day I die I would take it.

Scary or thrilling is preferred, but anything is fine as long as it's significant to you.... Mine was about a knock off Ronald McDonald that wore brown yellow and white instead of the usual red yellow and white. He had nasty teeth and made a weird noise that I can't spell. Kind of like a laughing gurgling sound. I would be chased around the outside of a skyscraper on a ledge only about 2 feet wide. When I would get to a corner I would have to slow down to round the corner and that's where he would always almost get me.

So I had an unusually long dream today and
towards the end, I received a message on my phone, but it immediately went away. I tried using the phone to respond to it, but it was glitching etc. Later I decided to text a friend to ask about it and the letters on the keyboard were all messed up and it felt like texting while really drunk. Every word looked like gibberish and autocorrect would mess up the words even more. It was really frustrating, has that happened to anyone else?
