Nightmares when drunk pls help

Okk so I am NOT a regular drinker I’m a social drinker and occasionally I might have a moment where I choose to drink on my own. But being the fact that I don’t drink often when I do decide to drink I get fucked. Like I need a whole bottle of Malibu to myself type of drunk. I have 1 main rule that i do my best to follow and have yet to successfully follow that rule and that rule is NO GOING TO BED DRUNK. I had a moment when I went to bed shit faced and idk what happened up I stopped breathing and flipped out in my sleep with a bad panic attack and ever since then I’ve stopped drinking so much in one sitting and not going to bed drunk. Yesterday night I decided to drink I got a 10 pack of fireball shots and downed 9 of them ended up falling asleep around 4am and was woken up at 6am For personal reasons And ofc I was still drunk sick and just tired. So I decided to lay back down around 7am to try to go back to bed still intoxicated and I did fall asleep. But this second time around was weird? Like very. I smoke a lot of 🍃 so my dreams are like non existent. But when do fell asleep I had a very extremely vivid nightmare that I can’t get out of my head. I have like death anxiety? I’m not scared of death just had a close call where I thought I’d die one day and it made me see how disposable we are to the world and I’ve been on edge ever since so this dream I had kinda messed me up if I’m gonna be honest. In my dream my bf and I were walking down a side walk to go to the gas station and we passed by this black truck in a turning lane getting ready to turn. We continued to the gas station and then left and walked back the way we came and the black truck was now completely wrecked the front good all smashed in and there were 2 guys standing out side the car perfectly ok. The drivers window and the back drivers side windows were rolled down and for some reason in my dream it like rewinds us backwards and we walk up the side walk back towards the black truck again but this time the 2 guys have their Body’s reaching into the truck through the window. Like when the windows down and instead of opening the door you lean over and reach in the car instead it was like that. They are resting there with their upper half hanging in the car and their lower half hanging out But both of their bottom half’s are severed and in extreme detail their guts and organs are hanging out it’s blood it’s extremely vivid and they are clearly dead I’m not the best at detail but it felt very real until I woke up and thankfully it was a dream. It freaked me out it’s been hours since this and I can’t get that image out of my head. I’m not sheltered by gore in any way I use to try to edgy as a kid and watched tf out of it when I was younger. But recently as I’ve said I’ve had weird death anxiety and this really just freaked me out. I went to google and google said alcohol can cause vivid nightmares. But I was wondering if this is something that’ll always happen? Or if I can prevent this from happening. As I stated I’m more of a smoker than a drinker and this honestly makes me just never wanna drink again. (I didnt re read so any typos I’m sorry I’m rushing typing this I apologize in advance)
