Constant nightmares after hangover

So I went on a binge for 5 days, after being sober for months, and ever since that last day of drinking; I’ve been getting nightmares and disturbing dreams when I fall asleep. So for the past few days, I have not been able to sleep. Google said it’s normal for 1-2 days for this to be happening but now I’m on day 5. I’m so tired and for some reason I can’t sleep. I have no history of insomnia or anything. When I finally sleep it’s only for a few mins before I have a terrible dream and I wake up. Anybody else experience this? How long did it take you guys for the dreams to go away?
