so I was taking a nap in the evening and I had a dream where I fell to the bottom of a lake and couldn't breathe. I started swimming to the top as fast as I could, and when I reached it, I woke up. But I was panting severely like I had actually held my breath for too long. My heart was beating super fast and I could feel my pulse in my throat and. It was like I just had a horrible panic attack or something. It took me a couple of minutes to calm my breathing. I don't know why I held my breath in real life and I was wondering if that's normal? It's never happened to me before. Also, I wasn't sure where to post this so don't come at me pls
