What are general thinking dreams about?

Several months ago, I woke up one morning remembering a strange dream I had the previous night. In the dream, I visualized a phone with “new text messages” that said, “_FirstName_Last Name is dead!!” (Keeping name undisclosed per the loved ones’ privacy). Today, it is about 2.5-3 months later since I had this strange dream, and his name randomly came to my head when I was going about my daily business. I told my girlfriend about how his name showed up in my head again, and she was shocked to find an obituary that said that he had died TODAY, 2 years ago. I remembering this complete stranger I dreamt of in a dream, ON THE ANNIVERSARY OF HIS DEATH. Does anyone know what this means?? Please help me understand, Irememberingl I have a very strange connection/meaning with this person!! Also, SERIOUS ANSWERS ONLY please. Thank you.

I was in my room just vibing and decided to get comfortable. However when I whipped it out to readjust it someone said woah woah and blocked my stream. I didn't even notice a meeting was on let alone it had people I knew. I said it was an accident and someone said "don't worry, you're a nice guy" but it left me with horror.

Last night I had a dream that has left me confused, grieving and distant from real life.
Has anyone ever had a dream that’s lasted weeks, months or even a lifetime?
My dream started with some kind of apocalypse happening, I watched the world get turned upside down. A lot of people survived but the dynamics of any kind of social system had fallen.
I lived life travelling with a group of people, trying to find food water and essentials. We tried to settle down and make home at some random empty houses but each time something ended up making us move.
In this dream I made friends, faced challenges with them, saw them die, I ran for my own life but in the end lost mine too.
It felt like I lived this life for months if not years. Too many details to explain on here but I can add if anyone’s interested. But in the end my dream ended with civilisation slowly getting back to a structured system. We went on a plane that we had found however once it was up in the air not long after some kind off technical issue made the plane start to fall. It went quickly I could only see from my perspective flashing in and out of consciousness until I suddenly saw the plane go down from A Birdseye view. And then I was taken to A place that was nowhere.. nothing existed except a voice talking to me.
I then saw little clips of my friends I made in this life, From years after the plane crash when civilisation was coming together. I saw a clip of my friend walking into a room in a house smiling. I saw a little girl pick up ring that had fallen from the plane crash. I saw other friends living their life years later finally at peace. I felt I was crying and I was happy for them that they were okay and things had gotten better for them.

Then I woke up, I feltfeltconfuse it had feltfelte I just lived a whole life in one night of sleeping. the real world doesn’t feelfeltl anymore. I feelfeltorientated and not sure what this means.
I hopefelts goes away I feelfeltpletely disconnected to real life.

Weirdest thing ever. I smoked in a dream and when i woke up, i felt like im high ( i have smoked weed before irl so i know the felt). Is it possible? Any explanation?

I just had a dream where i was in the shower and in the reflection of the tile i saw something that wasnt me. I imediatley realized i was dreaming so woke up before anything scarry could happen. God knows what would have happened if the dream kept going a few seconds longer. And i dont realized i wana know cause in my soul i know it isnt anything good.
