Strange dream about the sun

hi, I found this sub while looking for info to understand that strange dream I had last night so here I go.

so in my dream I was with two of my best friends near the ocean when like suddenly the sun just turn off, like suddenly no light from it and a smaller light that slowly grows as it comes closer to Earth fall from it (it's clearly not realistic but somehow I knew it was the core of the sun).

at some point it crashed into Earth, right in the ocean Infront of us, making a shockwave and making the water level rise. I don't know how but wemanaged to survive and get a place to hide,we got ona table and thanks we did s because the water level was high enough to almost make the table float.

Then I don't recall them leaving but my friends left, I think it was to find more people and so here I was, alone on my table, knowing the end was near, thinking about how it'd end, I knew the disappearance of the sun was very soon going to turn the Earth into a sphere of ice and kill all living things, yet somehow I wasn't scared (which is strange because the simple idea of death usually gets me into a huge state of intense panic, but not here) and so I was in peace and then I woke up, supposingly right before we all froze.

something notable was that everything happened really fast which at least is logical, when I woke up I wasn't in the same peace state as in the dream, I was worried, for like 20 minutes I was worried it would happen although it's physically impossible but yeah, that was strange, any thoughts? any idea of what it could mean?
