Terrifying Nightmare After Taking NyQuil

Alright I have a bit of a rant about my dream last night because it was terrifying and it's a bit.. graphic/descriptive so heads up. So I have a lot of trouble sleeping, I believe I may have insomnia, and so I really wanted to get some sleep last night and so I had the not so great idea to drink 1/4 of a bottle of NyQuil. It resulted in some REALLY scary and strange dreams unfortunately. More terrifying than normal because I get nightmares on a nightly basis. Tw on this next part I had an attempt recently to yeet delete myself off of this world, and my nightmare was that I had ODed (method I used during my actual attempt) on the NyQuil and I didn't know I was dreaming so I'm thinking in my head "why did I do that? I don't want to go." I was told I had a seizure when I tried irl but don't remember it because I was in a coma. In my dream I was having a seizure again, but this time i was aware it was happening and it didn't feel like something that was just a few minutes, it was carried out and painful. I really don't know what to do because I'm so so afraid of ODing on medication by accident again, but I need sleep. I'm so so tired because I barely sleep. Anyway, I don't know. thanks for listening to my rant.
