Strange physical feelings after prayer - could this be from Allah?

As-salamu alaykum. A bit of background: I’m very new to Islam and haven’t converted yet, but I’ve been seriously exploring it. I’m reading the Qur’an and feeling really inspired and pulled toward practicing. I’ve never felt a pull like this before. I was raised Christian but my family wasn’t very religious. We went to church sometimes; I was baptised and confirmed, but it never clicked for me - it was mostly cultural. I had some Muslim friends growing up who weren’t very practising, and I dated a Muslim boy at school who unfortunately used religion to scare and control me, which put me off for a long time. So I didn’t have any warm or positive experiences with Islam early on. For years I identified as atheist or agnostic. I tried non‑theistic satanism briefly as a way to feel empowered and later found Norse pagan stories interesting for their symbolism, but I never believed in those gods - I just liked the themes. Now the present: I’m going through a really hard time and needed guidance. I met someone while playing an online game and we clicked immediately - same interests, same fears. He’s a practising Muslim, and I only asked about his faith because I wanted to understand him. He suggested reading the Qur’an, helped answer my questions, and that sparked something in me. I wanted a sign from Allah that He’s real and that this might be the path for me. Today I tried prayer for the first time. I did wudu, found qibla and used an app to follow the Dhuhr prayer - listening to the recitation and reading along in English while learning the actions. It was hard and overwhelming, but I felt a calm, like a moment of meditation. Right after starting I felt very warm, like a hot flash. I kept praying and tried to connect with Allah, with the earth and with the universe. When I finished and lay down, a wave of sensation came over me - a tingly, warm, almost euphoric feeling that made me want to smile and felt like gently falling. I can’t really explain it. Maybe this was the sign I asked for - that Allah heard my prayer and is guiding me. Have any of you experienced feelings like this after praying? How do you understand it? I’m about to sleep after doing Isha, hoping for good rest. Thanks for reading and for any thoughts you might share.
