I think this is quite common, though it seems like the quality is just a tad bit different for everyone. So yeah, I feel something like it as well. It's not happiness, invincibility, or anger; it's more excitement, and a finale to look forward to, completely sober ofc. It's definitely enjoyable, almost intoxicating, lol.
Then it always leads me to start thinking about what comes afterwards: non-existence. What does that even feels like to not feel at all. It must be completely different from sleeping but even sleeping can feel already so... non-existent? I mean, it must feel exactly like how we felt before we were born, but what does that even feel like to begin with. It's creepy but interesting at the same time.
