What are sleeping dreams about?

Science has hypothesized the existence of parallel universes. What if sleeping makes us able to....I dunno....ride some wavelength of space / time / etc. into the first person of an alternate universe of ourselves? And what if, when we day dream, an alternate universe version of ourselves is doing the same thing to us?

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.

i had a dream where i was driving to my grandmother’s house & looked up at the sky to see Lucifer was in the sky and God was basically in hell. Lucifer’s horns were the shape of clouds but he was still in heaven and then God was on fire, so he was in hell (in my dream— i’m trying to be more specific about how it was). we all know it’s the other way around in real life and yet in my dream it was the opposite. and then as i was driving, God begins to chase our car and then he turns back around— he “turns his back on me” as i thought in the dream. i woke up from this dream at exactly 4:44AM. what could this possibly mean? i do believe in God. i pray to him all the time and he blesses me so i am quite confused, although as of lately i have been questioning Him but who doesn’t ??? but i also believe in the Universe— i practice spirituality, all the while believing in the Christian God because that is how things work for me. i have never had a dream of such entities until tonight and i am a bit afraid to go back to sleep because i don’t want to dream it again... if anyone could maybe give me insight on what this could POSSIBLY mean, please please let me know.

So, it was Christmas night and all through the house, I was sleeping and that’s all I care about. Anyway, I had three dream cycles that nights involving me waking up several times, but right before my second cycle ended the weird ass part of my mind cranked its motor.

It starts out with me walking out to some random patio, an open garden with a frame around it is in the center. While I’m walking down a few steps I start to hear a narration. “Mathematicians have this weird thing, where we scream at each other and then start kissing,” I keep walking and I see iguana size geckos coming out of the garden, and IRL I’m terrified of reptiles, so I try to avoid them. But they all start screaming like people, and the narration continues. “We keep screaming at each other and keep getting louder until one of us is the loudest. We call them the *forgot*,” then when I turn around something behind me licks my ear, makes a smooch noise, and screams like a “REEEEEEEEEEEEE” without the R.

I had a dream that I was visiting someone's house and was living there for a few days. Don't know whose house it was.
This middle aged woman, started showing interest in me.
We made friends quickly and were watching some TikToks with another friend. It was night, that friend fell asleep. Shortly after I fell asleep too. I woke up to the middle aged woman having sex with me.
I didn't know what the **** was going on so I went back to sleep.
Next day, we were doing the same, but this time, the woman sat on top of me like a sleep paralysis demon. And shortly after we started having sex again.
And... We got caught. Lead to a lot of controversy. That's when I started realising it was a dream and it became lucid.
Weird facts about the lady:
She was kinda ugly, and had 2 pairs of breasts.
Did I just have sex with a sleep paralysis demon?
