Your heart is pounding because there is a problem that you have neglected to take care of before going to sleep? It could be that the stress of the day has finally hit home and it comes out in your subconscious while you are sleeping. Finally, how do you know that your heart is pounding hard if you are asleep?

Sometimes your heart will pound while sleeping due to external reasons. You could have exercised to close to sleep time, consumed too much alcohol or other drug, or simply have had too much on your mind prior to sleep.
