Hey, does anyone else experience this during salah?

Assalamu alaikum warahmatullahi wabarakatuh. I wanted to ask about something I've noticed, especially since I started praying regularly around 16. When I pray or recite the Quran, I sometimes feel a bit overwhelmed. My heart beats faster, I feel a bit breathless and dizzy, my muscles get tense, and my head feels light. It's like my whole body reacts in a specific way. But right after I finish my prayer and make dua, it all changes. My heartbeat calms down, my body feels settled and relaxed-more than before, actually. The tension eases, my mind clears up, and I feel a cool, peaceful sensation. It's a very distinct shift. Has anyone else felt this? Is it something with a spiritual meaning or just how my body reacts? I'm not sure, so I thought I'd ask for some insights. Jazakallah khair.
