Are foam earplugs dangerous with overuse?

Sometimes when I lay down at night I can hear and feel my heartbeat in my ear. My blood pressure is a little low, but not dangerously low. What can cause this? Any reason to worry?
 
This is normal, if you plug your ears with your fingers you get the same effect.

You can literally "hear" the silence when you plug your ears, I can't explain the noise but if you plug your ears you'll understand.
