Is it normal to have hallucinations and insomnia after quitting drinking?

I just quit after a period of heavy drinking (about a week). I was feeling like shit. I tried getting to sleep, but when I kept my eyes closed for longer than a few seconds I would get these crazy hallucinations. They ranged from stuff like smiling faces of people I’d never seen, to stuff that looked like it came straight out of the Terrifier movies. I started falling asleep for a few seconds and immediately waking up in a start. Then I started having nightmares and when I would wake up I see someone standing in my room for a second. I didn’t get any real sleep.

I’m feeling better today and have been drinking tons of water, but I’m wondering If should talk to a doctor about it.
