I too sleep with earplugs in I've noticed something similar. When I take naps during the day and I use the plugs I find that it is the best sleep I get, I feel super refreshed. During the night when I sleep with earplugs in I usually don't sleep as well as I would without them (minus the loud roommates). But I am a side sleeper with a memory foam pillow so it tends to cause some pressure on my ears for prolonged sleep periods.
