Had a dream where i died like 3 times which I guess triggered a high heart rate then when I woke up felt my hr fast then panicked then that triggered a panic attack where i had to splash my face with water and clam down with deep breathing but my hr was so high i didn't see what it was but i could feel it when the hr was high my heart was still in rytem tho it didnt feel out of it i am scared it will happen again is this normal?
