Could be many things: When we are laying down to sleep we notice our heart rates more than while we are moving around during the day. If your heart rate is going fast, that could be from different reasons, like medications, dehydration, stress/anxiety, thyroid disturbances. If there is any associated chest pain or problems breathing, see your doctor for evaluation.

No one answer: Premature beats often occur when the heart rate slows, such as when you go to bed. Most often these are benign but can be bothersome. Sudden rapid heart beat which then stops abruptly might represent an abnormal heart rhythm such as supra ventricular tachycardia. Very often people feel their own normal heart beat when they are anxious.
