Weird feeling drunk closed eyes

I normally never post so idk what to say exactly but i am SUPER curious about this and if other people experience it.

So basically when i am drunk or stoned (i don’t experience this with any other drug) and i close my eyes. Sometimes i will have this weird feeling. It build up and has a peak, like an orgasm but it isn’t sexual. It feels good though. It’s like reaching a peak in relaxation sort off and i can’t force it, i just sometimes have it? I feel i could have it rn if i closes my eyes tbh. It’s hard to describe idk. Maybe like a peak. In dizziness, it feels like also maybe your eyes rolling bakc? Idk. Please tell me if u know anything. Thank you in advance.
