You finally lie down.
The day is over. The lights are off. Your body should be relaxing.
And then it happens.
Your heart suddenly feels… louder.
Stronger.
Faster.
It’s not always extreme, but it’s noticeable enough that it grabs your attention.
You become aware of every beat.
And almost immediately, your mind starts asking questions:
“Why is my heart racing when I lie down?”
“Is something wrong?”
The more you notice it, the more intense it feels.
And now, instead of relaxing, you’re alert.
If this has been happening to you—especially if you’ve already had normal checkups and tests—you’re not alone.
And more importantly, this experience is far more common than people realize.
And it’s not actually about your heart.
