right now it's 3:28am. i just woke up with my heart pounding as if i just sprinted 50yards. i had these episodes off and on through out my life. but tonite it felt really scary.my heart was literally pounding and i thought it was going to explode. is it possible to get anxiety in your sleep? or is it something else?another thought came to mind was did my heart stop while i slept for a few seconds and after i got out of bed did my heart start working again? i did see a doctor in the begining of the year after an episode like tonite happend.i did breathing test,blood work, a full screening. it turned out that i am in good condition. should i go and see a heart specialist? i must sound ridiculous but thats just what im going through righ tnow.
