It is unlikely that you had a heart attack in your sleep/dream. If you have a family history of heart conditions, smoke, recovered from Covid, have high cholesterol or blood pressure , or still have concerns - connect with your doctor, who can review your history and prior tests, perform an exam and possibly further tests such as an exercise test or imaging of your heart. Hope this improves soon.

It is quite possible you experienced an acute anxiety episode triggered while sleeping. This is not that unusual and can convince a person they are having a heart attack. I recommend checking in with a mental health expert or primary care provider to assess for other possible symptoms of anxiety or related concerns.
