3rd try, short breath, pounding heart Well few minutes ago I decide to give it a try, first I started with foucsing on breath then after there was tingling feeling in my both feet and my eyes was moving rapidly and there was like white thing I see from eyes while my eyes are physically closed , the thing is that made me open my physical eyes was the heart felt like I was sprinting and feels like it was about to pop out of my chest, even when I opened my eyes physically it kept pounding for 5 seconds I'm not sure how many seconds but that what I was able to count , right now I still feel the tingling in my feet, even after I opened my physical eyes, please help,share what do in case my heart pounds like that again.
Forgot to mention this process took me almost 30 minutes from laying flat on bed till I became fully aware


and update: after an hour and a few minutes, i started to feel slightly dizzy, Like when i wake up from sleep.
