Anyone have this experience with nitrous

Okay, so two nights ago I consumed roughly three 2,000 g nitrous tanks in combination with a bottle of wine. I went to sleep for about an hour, and when I woke up, I was screaming because I saw what appeared to be a figure in my room. I’ve been awake since, and it’s now been about two days. Since then, I’ve been extremely hypervigilant and flinching at even minor sounds or movements, hearing things that seem to be coming from inside the walls, and generally feeling internally panicked and on edge.
I’m also currently taking 1,800 mg of lithium and receiving the 400 mg Abilify Maintena injection. Could either of these medications affect my reaction to the nitrous and alcohol, or potentially contribute to the symptoms I’m experiencing?
