Weird Dreams

This is gonna be longer so I'm sorry for that and any spelling errors in advance. Also if your sensitive to the talk of death and suicide pls don't read thank you

So I keep having nightmares very frequently. Sometimes when I lay my head down on my pillow I can hear my own thoughts echo in my head, except it sounds like its coming out if broken headphones. Everytime I try to take a nap I keep having nightmares. I've had 6 nightmares in a total of three naps. So I'll tell each dream that I've had so far and I don't know what they mean

-My first dream-
I was in a barral of gasoline and I was stuck. Soon after while I'm still in the barrel of gasoline and it was lit on fire
-My second dream-
I'm dying on the floor, but everyone else I know is in the same room as me. I kept trying to get them to look at me as I was telling them I'm gonna die but no one paid attention. So I had just died on thr floor
-My third dream-
I fell down a big black hole. At the end of the black hole was an endless pit of water. I drowned in the water.
-My fourth dream-
My head was cut off by a fan blade. Thats all there was fr
-My fifth dream-
I overdosed from benedryll on purpose in that dream. I died from overdose
-My sixth dream-
I was in a pure white area, then I heard a voice say oh no! After that the vouce said close your eyes. The area went pitch black after the voice had said that. When it went pitch black the voice said do you wanna know something? I woke up soon after and didn't get to hear the voice finish

If you made it this far thank you for listening! I don't know, but I feel like I might be going insane somehow. I've also heard bells b4, like the cat toy type but my cats asleep at the time. It sounded like it was in my room but I think ut was just my head again. Also hope everyone has a great day/night
